Introduction
TM500 Power Cable Fault Locator adopts international advanced electronic testing technologies and SCM technology, and combines low-voltage pulse reflection and pulse current testing methods, is suitable for the precise range finding of power cable high resistance, flashover, disconnection, and low resistance.
Low-voltage pulse reflection method applies to test the range of the low resistance and broken line, and the length and wave velocity of various cables. Pulse current testing method can be divided into breakthrough high-voltage flashover and DC high-voltage flashover for the high resistance and flashover cable fault finding.
