ECN Forum Forums Technical Discussion Electrical Theory and Applications increasing primary voltage

The secondary voltage is proportional to the primary voltage. So, for example, if the current output is 480 V, the ratio is 13800/480=28.75. At 14.4kV, the output will be 14400/28.75=500.9 V.

A simple equation you can use:

New output = (Current output/Current Primary) * New Primary
