EXTRA HIGH VOLTAGE SUBSTATION CONNECTORS
We have been actively engaged in the design, development and production of substation power connectors for Extra High Voltage (EHV) applications since 1957. The experience gained through research and development in designing substation connectors for use at low voltage levels helped in planning ahead for the EHV era. The use of Extra High Voltage has evolved as an economic necessity rather than a glamorous alternate. With large generating stations being located at fuel availability points in remote areas, plus the requirement for utility interconnections, the need is increasing to transfer larger and larger blocks of power over greater distances. Extra High Voltage was and is necessary; however, existing designs of equipment and connectors had to be altered to handle the higher voltages. EHV connectors must operate free of corona and maintain the mechanical strength and current transfer capabilities required of other power connectors. As an established leader in the Extra High Voltage substation connector market, we were one of the 345 KV connector pioneers and the first manufacturer to supply connectors for 500 and 765 KV substations. And, a major percentage of the EHV connectors in service today were designed and supplied by us. Our continuing efforts have aided the electrical industry in the development of design standards and performance criteria for these connectors. Our goals coincide with those of the electric utility industry…to provide an ever improving product at the lowest possible price. Nature of Corona and RIV Corona is the primary element which must be considered and controlled when designing connectors for Extra High Voltage applications. Corona is a result of a condition where the electrostatic flux density in the air exceeds a critical value near an adjacent metal surface. Air and other vapors in this area become ionized and serve as a conductor of electricity. When the voltage is increased, a brush discharge takes place, until the whole thickness of the dielectric layer is broken down and disruptive discharges (sparks) jump from electrode to electrode. Corona involves power loss, radio noise and can have an injurious effect on fibrous insulation. Sharp edges, bubbles, nonhomogeneous insulation, etc., aggravate this condition. Positive corona can be seen as a plume and is the principal source of radio influence voltage (RIV). Negative corona is seen as a glow and has no significant radio influence. EHV connectors must be free of audible and visible corona at the rated line voltage plus ten percent. At these voltage levels the RIV level should not exceed 200 microvolts. Design Criteria The design of Extra High Voltage connectors and fittings must meet critical field gradient configurations in conjunction with the mechanical and/or electrical load carrying requirements. Failure to meet this prerequisite can result in unacceptable visible or audible corona. We control corona on substation connectors by providing recessed hardware, generous mass and radii, high quality surface finish, and shielding rings. Any or all of these designs could be used in any given application requirement. All Extra High Voltage components are manufactured within our facilities, utilizing proven production techniques. These procedures plus final assembly, inspection and packaging, are geared to preserve quality and acceptable connector performance. As a result of our design efforts, testing and experience, EHV connectors and connector assemblies are free of audible and visible brush type corona at voltages ten percent above rated system operating voltages. Years of experience in the EHV substation connector field has indicated it is most advantageous to the purchaser to obtain all EHV substation connectors for a single station from one manufacturer. This not only provides design and manufacturing integrity through all the connectors, it also provides unit responsibility. This single source minimizes the amount of effort on the part of the customer and should any questions arise during construction or subsequent operation, experienced factory personnel are available to assist in resolving questions concerning our connectors. Various standards, test and experience in the EHV field indicates there are minimum conductor sizes which should be considered in the design of 345 KV and 500 KV substations. Tubing smaller than 1 1/2” IPS or cable less than 1.76 inch diameter should be bundled for 345 KV application. Conductors smaller than 2 1/2” IPS or 2.50 inch cable diameter should be bundled for 500 KV application. Based on extensive laboratory testing and many years of experience, we can recommend the most efficient connector and conductor system to meet your requirements.

EHV SUBSTATION CONNECTORS- Continued
Radio Influence Voltage (R.I.V.) and Corona Testing Corona observations are made in a darkened laboratory using binoculars. A voltage is impressed upon test specimens to cause sufficiently violent corona discharge to identify areas of high electrical stress. Corona observations are made and recorded as the impressed voltage is decreased in small increments. Observers also monitor the absence or presence of audible corona. All of our basic designs have been tested for satisfactory corona free performance and have consistently performed above the minimum acceptable limits currently specified by every utility and consultant with whom we have worked. Without exception, all material which we propose to furnish is capable of corona free performance within normal R.I.V. limits at specified voltages. Conclusion We have frequently been called upon to custom design for special applications at various voltages. Many customers have found that our catalog listing is only a small segment of the vast collection of connectors and fittings which we have produced for utilities across the country. We have the production capability for producing to customer specifications and the design knowledge and experience to make sound recommendations for connector application. Our capabilities have been proven by the outstanding field performance record enjoyed to date and we are justifiably proud of this record. We sincerely appreciate your interest in our Extra High Voltage connectors and will welcome the opportunity to provide further information in any area in which questions may arise.

EHV SUBSTATION TERMINALS
EHV SHORT BARREL COMPRESSION TERMINALS FOR CABLE TYPE CCLS-EHV Aluminum cast compression terminal connectors are designed for corona free service at 500 KV. Single cable diameter under 1.76 inch for 345 KV and 2.50 inch diameter for 500 KV may not be corona free unless conductors are bundled. These connectors can be compressed with conventional tooling. The barrel is factory inhibited and the entire connector is sealed in a clear plastic bag. Tongue mounting hardware and bolt shields are not part of this catalog number, and must be ordered separately. Pads are pressed and have contact surface on both sides. Shot barrel requires less space and allows faster installation. Pad holes have NEMA spacing. Contact sealant is recommended. For 15˚ angle terminals add “-15” to catalog number (example CCLS-1424-D-15) Material: Casting – 99 aluminum alloy
For use with conventional compression Tooling, refer to chart C-13282 for tool and die information see page 86. Add “-XY” for double contact surfaces.

WELDING ALUMINUM BUSES AND CONNECTORS
Recommended welding procedures to ensure a sound weld are as follows: Pure aluminum melts at 1220˚F while aluminum alloys melt in the range of 1020˚F depending on the alloy content of the particular metal involved. When aluminum alloys are heated there is no color change. This makes it difficult, if not impossible, to tell if the metal is near the welding temperature. The ever present surface oxide films on aluminum have a melting point of 3600˚F. The parent aluminum or aluminum alloy can therefore be melted without fusing the surface oxides. Unless the film is removed, cleanliness of the molten filler metal and the parent metal cannot be complete and both strength and conductivity may be sacrificed. Therefore, it is of prime importance that the aluminum oxides be removed from the aluminum alloys before welding is started. In the shielded are welding method the shielding gas has a tendency to clean the material as welding progresses. CLEANING OF BUSES AND FITTINGS It is very important to remove all greases and oxides from the surfaces to be welded. This can be accomplished by using a mild alkaline solution or standard degreasing solution. The preferred method is to use a stainless steel wire brush and vigorously scrub the surfaces to be welded. The stainless steel brushes are specified because the stainless steel has less of a tendency to pick up particles of aluminum and aluminum oxides. WELDING METHODS Anderson recommends the following two types of welding methods for welding aluminum fittings and buses: 1. TUNGSTEN-ARC WELDING (TIG). The inert gas shielded tungsten-arc process is widely used for welding aluminum bus fittings. In this process the arc is established between a non-consumable tungsten electrode and the section to be welded. Inert gas envelopes the arc to prevent oxidation during welding. Hence, no flux is required. A bare filler rod supplies filler metal to the weld area. To initiate the arc the tungsten electrode is placed in contact with the component and then withdrawn to establish an arc length of approximately 3/16”. The arc is given a circular motion until the base metal liquifies and the weld puddle is established. Filler metal is added by hand as required. In this process, if more than one pass is required for a sufficient weld, the weld should be wire brushed between passes to remove any surface dirt or oxides which have accumulated from the previous pass. Since no flux is used the finished weld does not require cleaning. In this process the heat of the tunsten arc is concentrated in a smaller area and is much faster than the conventional type of welding and distortion of the weld is negligible since the heat is concentrated in a small area. In this process, if thicknesses greater than 1/2” are to be welded, preheating of the parts before welding will increase the welding speed. 2. METALLIC-ARC INERT-GAS SHIELDED WELDING. The consumable electrode inert-gas shielded metal arc (MIG) welding process combines the advantages of tungsten-arc welding with increased welding speed. Welding can be done from any position and the process can be either manual or automatic. Manual welding techniques are somewhat different from other methods. However, a welder can be trained to use the MIG process with only a few days concentrated training. In the MIG process the bare filler rod is supplied as a coil of bare wire. In the commercially available equipment this wire is added to the weld at a predetermined rate by a motordriven feed that can be adjusted to the magnitude of the welding current. In this process, as well as the tungstenarc process, gas forms a shield around the arch to prevent oxidization during welding. Either helium, argon or a mixture of helium and argon are suitable shielding gases. Pure argon is most widely used on sections less than 3/4” thick. On sections over 3/4” thick the gases are usually mixed to combine the hotter arc characteristics of helium with the stabilizing effect of argon. If exceptionally hot arc characteristics are required, pure helium can be substituted for the gas mixture. Precaution should be exercised if this substitution is made in that it is very easy to burn through the items that are to be welded with a pure helium atmosphere.

WELDING ALUMINUM BUSES AND CONNECTORS
The reasons that Anderson has selected the metallic-arc inert-gas shielded welding method is that in this process the filler metal can be automatically fed through the welding mechanism and eliminates holding the electrode holder in one hand and the filler metal in the other as in the tungstenarc method. Figure 1 of the attached drawing shows the basic components for a metallic-arc inert-gas shielding process (MIG) and Figure 2 shows the basic components for the tungsten-arc process (TIG). As it is readily apparent, the basic difference between the two types of welding apparatus is the automatic feeding mechanism for the filler wire. In both types of apparatuses the electrode holder and the welding gun can or cannot be cooled by water. If welding currents of more than 125 amps are required, both methods will have to add water cooling apparatuses to the electrode holder and the welding gun. WELDERʼS QUALIFICATIONS No welding should be done until the operator has had experience with welding aluminum alloys by the methods described above. Men with previous experience in metal welding should be selected for training in welding aluminum for a period of training of not less than one week after which time the man can be considered proficient in the use of the equipment and in the welding of aluminum joints. After this period, there should be no difficulty experienced in welding aluminum alloys. It is suggested, if practical, that welders should practice on actual fittings or buses before proceeding with the welding of the required job. The following is Andersonʼs recommended specification for current fittings, wire feeds, gas flows, etc. These specifications are of a general nature to the extent that many factors have to be considered such as: 1. Type of equipment used, whether water cooled or not, etc. 2. The size and mass of the piece to be welded. 3. The position of the weld. 4. And most important of all, the operatorʼs skill. 5. All persons in the welding area should wear the proper shields. The arc is approximately twice as strong as the standard AC welding arc. Extreme caution should be exercised for the protection of eyes.

GENERAL WELDING SPECIFICATIONS FOR CONSUMABLE ELECTRODE WELDING METHOD
SCOPE: This specification applies primarily to welded aluminum connectors for substation construction. MATERIAL: CASTINGS – As furnished by Anderson are molded from 356 aluminum alloy and heat treated to T6 condition, or #99 pure aluminum depending on the application. FILLER ROD – 4043 aluminum alloy 1/16” diameter for all joints as shown in the Anderson catalog. SHIELDING GAS – Argon. WELDING APPARATUS – Tungsten-arc (TIG) or metallicarc inert-gas shielding (MIG). A 400 amp welding machine with reverse polarity is capable of handling the majority of aluminum welding jobs. PROCEDURES: It is of the utmost importance to remove oil, grease, water and oxide from the surfaces to be welded. All surfaces to be welded should be wire brushed with a stainless steel brush prior to welding. If more than one weld pass is required, the original weld should be wire brushed before applying additional weld. Pre-heating of surfaces to 400˚F is optional, but by preheating the surfaces before welding it is possible for the operator to weld easily and faster.

Transmission & Distribution

...Transmission subsystem • Distribution subsystem We distinguish between these various portions of the power system by voltage levels as follows: • Generation: 1kV-30 kV • EHV Transmission: 500kV-765kV • HV Transmission: 230kV-345kV • Sub transmission system: 69kV-169kV • Distribution system: 120V-35kV The distribution system may also be divided into three distinct subsystems. • Distribution substation • Primary distribution system • Secondary distribution system Distribution substations The distribution substation receives power from one or more transmission or sub transmission lines at the corresponding transmission or sub transmission voltage level and provides that power to one or more distribution feeders that originate in the substation and comprise the primary network. Most feeders emanate radially from the substation to supply the load. There are five main functions of the distribution substation: 1. Voltage transformation: One or more transformers will always be located within the substation to step down the voltage to the primary distribution voltage level. These transformers will always be three-phase banks, or they will be three single-phase banks connected in a three-phase configuration. 2. Switching and protection: Different kinds of switchgear will be located at the substation, including the following: a. Switches: devices that can carry and interrupt normal load current and thus disconnect portions of the network. b. Circuit breakers:......

765 Kv Transmission System in India

...Prof. R. N. Ganguly along with my fellow batchmates who provided valuable support and co-operation during the execution of project. Introduction The basic function of a transmission system is to transfer electrical power from one place to another or from one network to another network. A transmission system includes the terminal substations, transmission lines and intermediate substations. Transmission systems are required for ● Transfer of bulk power from large group of generating stations upto the main transmission network ● System interconnection ● Transfer of power from main transmission from the main transmission network to secondary substations The increasing need of transmitting greater and greater amounts of power over long distances has led to a continuous increase in transmission voltages. As a rule, larger the amount of power to be transmitted, higher is the requirement of transmission voltages. In India, the transmission voltages in use are 33, 66, 110, 132, 220 & 400 kV . The next higher voltage of 765/800kV has been selected for transmission of huge blocks of power from generating stations to load centres. Necessity of EHV Transmission Reduction of Electric Losses , increase in Transmission efficiency , inprovement of Voltage Regulation and reduction in Conductor Material requirement For transmission of given amount of power over a given distance through the conductors of a given material and at a given power factor as the transmission voltages......

Grid of the Future

...significant share of local loads in may future distribution networks. This will permit to ensure higher reliability and a faster recovery from outage situations. • Operation of storage and other new small-scale network participants providing services needs to be integrated into grid management tools. The computational challenge of managing this rising number of resources shall not be underestimated. • Integration of a large number of distributed and renewable generators will require plug and play style network connection (thus lowering the associated engineering efforts). A number of prestandardization efforts have been started into this direction. Microgrids solutions have been successfully implemented in the past, e.g. using AREVA T&D’s Pacis substation control system. The technical viability and the added value for sensitive users could thus be established. However, such systems remain the exception in current systems, and more effort will be necessary to encourage utilities to use MicroGrids at a larger scale. A second early example of a modular system permitting the integration of a larger number of distributed participants are D-STATCOM systems. E.g. an SVC MaxSine dynamic shunt compensation device has been delivered by AREVA T&D to a steel processing plant near Abu Dhabi. The 72MVAr AREVA T&D SVC MaxSine provides high customer benefits: thanks to the improved power quality, the steel processing plant could increase the power it receives from the network, thus......

Sub Sysnchronous Resonance

...points in the frequency scanning plot of the system reactance that identify network configurations with SSR problem are those where the reactance is zero (series resonant point). III. Case Study The developed tool was applied to analyze the SSR phenomenon on several steam driven turbine-generator plants in the northern part of the Western System Coordinating Council (WSCC) area where several 500kV-transmission lines have series capacitor compensation. The study was performed to evaluate the SSR for credible contingencies that may lead to a network topology susceptible to SSR phenomenon. For the purpose of including only those components that are of importance to the SSR screening study, a study system was created to include the HV and EHV transmission network in region under study and control areas with direct ties to that region. After Network reduction, the study system includes 712 buses, 147 loads, 1269 branches, 246 generators, 6 control areas and no HVDC terminals.
