When the power supply waveform is distorted, in the vicinity of zero point of the AC power supply in particular, I want to confirm that the rise of the voltage does not become unsafe mode or outage when steep.
Deactivate upon when distorted power waveforms, especially in the vicinity of zeros of the AC power supply voltage a precipitous or to see things not in unsafe mode.
When a power supply wave pattern was warped, in the vicinity of the point zero of the AC power supply in particular, I confirm that it isn't in breakdown or a non-safe mode when a start of the voltage is steep.
