Product Features

High voltage pulse gennerator XHHV535-2L

mainly used for shock discharge during low-voltage cable fault testing. The pulse generator adopts humanized design operation mode, high-precision dedicated high-voltage electronic components and high-frequency high-voltage technology, which is easy to operate, light in weight and easy to carry. It integrates the energy storage capacitor, DC high voltage source, and discharge ball gap. The operation of this equipment is safe and reliable, with automatic protection functions of over-current, overvoltage and overheating, it can truly achieve the effect of not being damaged by impact, and it can also work normally with high voltage to ground. Low voltage pulse generator is equipped with a time relay, and the discharge time interval can be arbitrarily set within 0-100 seconds. When working, the high-voltage pulse output is uniform and controllable, high-voltage side voltage measurement, make the result real-time and accurate. Unique high-voltage measurement design, in the stop state, the voltmeter can indicate the capacitor voltage in real time. The user can observe the residual voltage while discharging, until the voltage value returns to zero, and finally make the discharge more thorough.

cable fault pinpointer XHDD503C
Cable fault location instrument uses the acoustic and magnetic synchronization method to determine the power cable fault point. The electronic flashover is generated by the impact discharge generator, picked up and amplified by the corresponding probe, and the precise location of the fault point is determined by auditory and visual judgment.
It is a device that completes the precise positioning of the cable fault point within the rough measurement range and collects the acoustic and magnetic time difference. It integrates positioning technology, path-assisted testing and other technologies, providing multiple test modes and rich and diverse prompt information to efficiently and accurately complete cable fault location
