Medium and low voltage underground cable fault locator set
1.Working priciple and steps:
1.Use DC or high-voltage pulse to make the cable fault point flash over and discharge
2.Use the traveling wave reflection principle to make a rough measurement of all types of cable main insulation faults
3.Use the acoustic-magnetic synchronization method to make a precise measurement of all types of cable main insulation fault.
