KDJK-20A overhead line grounding fault inspection device is composed of three parts: signal generator, collector (high-precision clamp meter) and handheld PDA(APP). Suitable for 10kV overhead line single-phase grounding fault search, especially for porcelain bottle breakdown, arrester breakdown and other hidden grounding fault location accurate, search fast. The collector and handheld PDA can also be used for single-phase load current measurement. The product has the characteristics of lightweight structure, simple operation, accurate positioning, convenient load current measurement and so on.

1, through the insulation rod operation, internal fuse protection device, safe and reliable operation.
2, the device is equipped with the output function of the swing meter, which can find the single-phase grounding fault caused by high resistance grounding.
3, built-in built-in large capacity lithium battery power supply (car charging), no need to provide additional power, easy to use, durable.
4, the signal generation device can be configured with one or more groups of signal acquisition receivers, which can further improve the search speed.
5, the current acquisition and receiving wireless antenna is built in to ensure that the clamp meter is absolutely insulated and reliable, handheld PDA(APP) positioning system.
6, backlight display can be set, easy to use at night.
7, small size, light weight, simple operation, easy to carry, 4 pieces of equipment.
