About this file
This document is a Salient Characteristics specification sheet for a 2000 KVA transformer required by 628 CES Electrical Systems shop to replace a leaking unit currently in service.
The transformer must meet the following core specifications: 2000 KVA capacity, liquid filled with non-PCB insulating fluid, pad mounted type, three phase loop feed configuration, and 60 Hz frequency. The primary voltage requirements specify 13,800 GRDY/7970 volts with primary voltage overcurrent protection via bayonet fuse and a standoff well bushing 200-amp load break elbow insert dead front configuration. The secondary voltage output must be 480/277V with live front threaded stud terminal paddles providing three secondary connection points (X1, X2, X3). The transformer shall include a 5-position voltage tap changer (2 above and 2 below system voltage) and a 4-position load break switch capable of loop feed only, loop feed with transformer, A primary with transformer, and B primary with transformer configurations. The enclosure must be tamper resistant, pad lockable, and finished in green color.
