GENERAL :The PCLC-901D Power Cable Fault Pre-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.
PCLC-901D can be used alone under the low voltage impulse mode.
Under the mode of impulse current,PCLC-901D needs to work with HVSG-500GX high voltage generator items.Under the multiple impulse mode,PCLC-901D also need PCLC-900C coupler.After distance locating,user could use PCLD-901P items for fault pinpointing. And these products can be combined into a set of high performance and innovative cable fault testing system.
Multiple distance locating method:-Low current impulse method: apply to the locating of the low resistance fault. Short circuit fault, open circuit fault. It also can be used in the measurement of the cable length, the intermediate joints, T joints, and cable termination joint. This method also can be used to correct the wave velocity.
-Impulse current method: apply to the high resistance fault, breakdown fault. Use the current coupler to gather signal from the earth wire
-Multiple impulse method: improvement of the SIM method
-Advance tech.Upgrading for SIM method
200MHz real-time sampling
-Max. 0.4m measurement resolution,PCLC-901D has small blind zone and is special for the short cable and nearly-terminal fault cable
-Touch operating screen with smart gesture operation
Touch screen and press key operation
-Support cursor drag-drop function and double-click function,easy to locate
-Simple function menus with high performance.
-Simple function menus with high performance

Testing range is the device measuring distance.
For TDRL or ARM(multiple impulse method):
For the initial testing, the range should be hundreds meters longer than the cable complete length, for example,if the cable is 1400m, it's suggested to choose 3000m but no 1500m. If the suspect point is close, it is suggest to reduce the testing range.
For Impulse current mode:
When initial testing,the range should be triple of the cable length. For example, if the cable is 200m, it is suggested to choose 800m.If the suspect point is close, it is suggest to reduce the testing range.
For testing range chosen:
Choose Range menu to choose different range, total 10 levels from min. 200m to max. 100km
