China 10V~550kv Wireless High Voltage Phase Detector Wireless Phase Detector for High Voltage Power Transmission Line Voice Wireless Phase Tester

General Information:
EP8210A Intelligent Wireless High Voltage Phase Detector contains wireless receiver, XY detector, retractable insulated rod and other components. The receiver contains a 3.5-inch true color LCD screen, which can show the phase checking results, phase, frequency, and vector diagram instructions at the same time, which makes it clear and intuitive. The phase checking distance on the open ground is up to 1600m far, full intelligent phase checking of the voltage line covers the voltage of 10V ~ 550kV, in which the bare wire voltage of 35kV and below can be directly conducted with contact phase checking, and the bare wire voltage of over 35kV can be directly conducted with non-contact phase checking. Noncontact phase checking is to make the detector closer to the wire under test, and when the electric signal is inducted, the phase checking will be completed. This method avoids direct contact with the high voltage wire, so it is safer! The phase checking instrument can also function as high-voltage electroscope, high-pressure phase meter and high-pressure phase sequence meter, which can be used for testing electricity, phase sequence test, transformer group judgment and so on.
