In 2500kva transformer how much is the withstand High
voltage power frequency between primary to secondary and
earth? And secondary to primary and earth?

Answer Posted / ashwani malhotra

The question is somewhat wrong. Because high voltage power
frequency depends upon the rated voltage not on the
capacity. Like As per IS 2026 for 12 kv level specified
value is 28 kv.So for detail refer to IS 2026 part I
