Single Phase Traction Transformer Transformers

132/25 KV Single Phase Traction Transformer

This transformer is installed in a traction sub-stations along side the rail track and is used to feed 25KV AC power to railway electric locomotives.

The 132 KV winding is connected to two nominated phases of incoming three phase lines and on the secondary side, one terminal of 25 KV winding is connected to the traction overhead equipment while the other is solidly earthed to the running traction rails. This transformer is designed to meet overloads up to 200% for specified duration and dynamic/thermal short circuit of 0.5sec and 5 sec respectively.
