How is the cable fault tester powered? The instrument adopts low-voltage pulse method and high-voltage flashover method for detection, which can test various faults of cables, especially for cable flashover and high-resistance faults. ,precise. The instrument adopts low-voltage pulse method and high-voltage flashover method for detection, which can test various faults of cables, especially the flashover and high-resistance faults of cables can be directly tested without burning through.
If equipped with a sound measuring point instrument, the precise location of the fault can be accurately determined. The cable identification instrument host is powered by AC 220V. The cable identification instrument signal generator is powered by AC power, and it applies a fixed period unipolar DC pulse to the cable to be identified that has been de-energized.
However, there is one thing to pay attention to. You must pay attention to the use environment. Insulate and protect these live parts to avoid safety problems caused by long-term discharge. Generally, the reading of the meter will be considered. The current size is determined by the loop resistance, and the loop resistance should be as far as possible. Small.
