Induction Furnace Transformers

Depending on rating of the rectifier transformers, input voltage is derived from standard three phase AC distribution voltages like 433V, 3.3 KV, 6.6 KV, 11 KV, 22KV, 33KV etc. These become the primary (or line side) voltage of transformer. Secondary (or cell side) voltage can be between 400 to 1000 V decided by the required D.C. output voltage.
