Protectors are required to break down within ±25% of
the manufacturer’s specified breakdown range but no higher than 750 V at

2 kV/s rise
time.
2. Endurance Conditioning — Protectors are subjected to 500 impulse cycles. Each cycle is
a 1000 V peak, 10 A, 10x1000 µs pulse. Pulses are applied in one polarity at 10-second
intervals and then repeated in the opposite polarity. Then, 100 cycles of 1000 V peak,
100 A, 10x1000 µs pulse are applied to three new protectors. Finally, two cycles of
