In this professional guide, we demonstrate the XHGX507 Underground Cable Fault Pinpointer in action. Watch as we show you how to locate high-resistance cable faults up to 2MΩ using the step voltage A-frame method, trace live cables with the coupling clamp, and utilize the dual-frequency transmitter for various field conditions. You'll learn practical techniques for pinpointing insulation faults in street lighting and power distribution networks without high-voltage equipment.
