Three Phase Pad Mounted Transformer


Farady Electric’s three phase pad mounted distribution transformers provide a reliable and affordable solution for clients who need to reduce their overall operating costs. They are low-profile, compartment-type transformers, which are generally used for step-down purposes from an underground primary cable supply suitable for mounting outdoors on pads without additional protective enclosures, and meet the following standard: IEC60076,ANSI/IEEEC57.12.00, C57.12.20,C57.12.38, C57.12.90, BS171, SABS 780 etc.

The transformers described herein are designed for the application conditions normally encountered on electric power distribution systems. As such, they are suitable for use under the “usual service conditions” described in IEEE Standard C57. 12.00 general requirements forliquid-immersed distribution, power
and regulating transformers.
