Dry Flashover is the level of voltage applied to a equipment body of having outdoor applications in dry condition, at which the flash over occurs between the phase and grounding part of the equipment.
Wet Flashover is the level of voltage applied to the equipment at wet condition, inwhich the flash over occurs.
The fanda behind this is equipment will have higher Dry Flash over voltage then the Wet flash over voltage.

A 100 kVA , 400 v/250 kv testing transformer has 8% leakage reactance and resistance on 100 KVA base . A cable has to be tested at 500 kv using the above transformer as a resonant transformer at 50 hz . if the charging current of the cable at 500 kv is 0.4 A find the series inductance required . Assume 2% resistance for the inductor to be used and the connecting leads . Neglect dielectric loss of hte cable . what will be the input voltage to the transformer ?
