The HZGZ-S Transmission Line TDR Cable Fault Locator is engineered for rough 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.
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 needed for precise location. Together, these components form a high-performance cable fault locating system with a range of innovative features.
