Xtester-CD7505 Cable fault multi-impulse coupler
Overview
Matched with CD-650 HV generator and CD-750 pre-locator to do location of the power cable high resistance leaking fault, flash fault, low resistance fault and break fault.
CD-7505 Cable fault multi-impulse coupler is used to offer the multi-impulse signal coupling path for the cable fault locator. It adopts the latest multiple impulse method to simple the judgment of the cable fault waveform.
It transfers the complex voltage surging breakdown waveform into the easy distinguished fault waveform. And the requirement to the tech. stuffs is reduced. |
