Insulation requirement:
1. The full wave withstand voltage (peak) of primary winding lightning impulse (internal and external insulation) is 75kV, and the lightning impulse cut-off withstand voltage (peak) is 85kV.
2. The withstand voltage of the end of the primary winding to the secondary winding and the ground frequency is 3kV, 1min.
3. The frequency doubling induction withstand voltage of the primary winding is 30kV, 40S.
4. When the partial discharge level is 33.6kV (square mean root value) and the measured voltage is 14.4kV, the apparent discharge quantity is not more than 20pC respectively.

Service Environment
