2 The following electrical ratings are typical: Primary voltage: 69 kV Transformer kVA: 500 20,000 kVA Secondary voltage: kV kVA Primary unit substation is defined in the following standards: NEMA Standard No. 201-1982 IEEE Standard No. 100-1977 Primary unit Substations are used to step down utility distribution voltages to in-plant distribution unit substation transformers are designed, manufactured and tested in accordance with applicable IEEE a result of locating power transformers and their close-coupled equipment as close as possible to the areas of load concentration, the Secondary distribution cables or bus-ways are kept to minimum lengths. This concept has obvious advantages such as: Reduced power losses Improved voltage regulation Improved service continuity Reduced exposure to faults Increased flexibility Minimum installation cost Efficient space utilizationAdditional advantages of eaton s unit Substations in this unified approach are.

3 Single-source responsibility Complete electrical and mechanical control over coordination of the three close-coupled sections Availability of all switchgear types as secondaries gives broad application flexibility Modern design Composite assembly retains proven safety and integrity of each of its three major partsPrimary unit Substation Transformer Liquid-FilledEasier to SpecifyStandardization through IEEE standards results in proven designs with complete accessory equipment and Short-Circuit StrengthHighly researched and thoroughly tested designs provide the short-circuit strength necessary to withstand the repeated large short-circuit currents that are available in modern Handling and Reduced MaintenanceCompact designs reduce the cost of rigging and hauling and require smaller installation space.

An ATC uses a cable connection on either the Primary side, Secondary side or both, and is placed between the transformer and the remotely mounted Primary or Secondary Liquid-Filled Indoor/Outdoor Using Air Terminal Chambers Top View1 Radiator position and number of radiators will vary based on Primary or Secondary ATC or Transition Section Dimensions in Inches (mm) Note: Minimum ATC widths by kVA are listed in the table above.
