The HZGZ-103 Multifunctional Digital Underground HV Power Cable Fault Locator is a portable, intelligent device designed to locate power cable faults when used with a high-voltage signal generator. It integrates multiple fault location methods — including the acoustic and magnetic synchronization method, the step voltage method (optional), and the magnetic field intensity method — which work together to ensure precise fault location.
