03).PIPE LOCATOR SPECIFICATION:
- The PCLC-906D Power Cable Fault locator is an easy operation device used for distance locating . It's easy to operate,support both touch screen/button operation and with friendly interface. Low voltage pulse mode (TDR ) can be used independently; In impulse current mode (ICM), it needs to be used with HVSG-500GN series high voltage signal generator; In the multiple impulse mode(MIM) must also be tested with PCLC-900C cable multiple impulse filter coordination; After the distance measurement is completed, the PCLD-904P series digital multifunctional cable fault pin-pointer shall be used for accurate point pinpointing. Together, they form a high-performance cable fault finding system that offers a variety of innovative features.
