| System function |
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
