The Working Principle Of Line Fault Indicator

Ground detection principle

Sample grounding capacitive current of the moment the first half wave with the first half-wave voltage at impact, comparing the phase when the grounding capacitive current mutations of the moment of sampling and greater than a certain value, and ground instantaneous voltage half wave phase, and wire for voltage drop, judge line grounding, or line is not earthed.

Short circuit detection principle

According to short-circuit; in the short moment power current positive mutation, protection as a basis for action.
