The HZGZ-S High-Voltage Power Cable Fault Locator is engineered for precise distance measurement of power cable fault points. It delivers easy-to-recognize waveforms, high resolution, and a user-friendly interface that supports both touch and mechanical button operation for straightforward, efficient use.
The low-voltage pulse method can be used independently. The pulse current method requires cooperation with a high-voltage signal generator, while the multiple pulse method additionally requires a multiple pulse coupler for cable testing. After distance measurement, a digital multifunctional cable fault locator is used for precise pinpointing. Together, these components form a high-performance cable fault locating system with a range of innovative features.
