This video explains the main functions and practical uses of the XHHV535-4Z Portable Cable Fault Locator in a clear, step-by-step format. You'll see a complete demonstration of how this high-voltage surge generator performs impulse discharge and withstand voltage tests on both low and high voltage cables. We'll walk through the integrated system's safety features, including automatic protection functions and zero-start protection, while showing proper setup procedures and timing parameter configurations to ensure safe operation.
