HTDR-H adopts a new generation of high-speed mixing microprocessors, highly integrated, simultaneous collect the tested objects’ voltage signals and current signals, automatically calculate the capacitance value, the inductance value and reactive power value. Field measurement capacitor without removing the connecting wire, simplifying the testing process, improve efficiency and avoid damage to electrical equipment. After finished the test, automatically calculate capacitance value of each phase and other parameters, can easily distinguish the capacitor quality and connecting conductors faults among components. At the same time, the instrument with data storage and USB communication functions, can ensure the measuring data integrity.
