ZC-820 High voltage detector up to 110 kV AC, used in power lines, phase tests and phase sequence tests for substations, with functions of phase testing, phase sequence testing, electrical inspection. With strong anti-interference ability, in line with (EMC ) standards, adapt to a variety of electromagnetic interference occasions. High voltage phase signal will be taken out by the collector, discharge directly after treatment. Received by instrument and compare the phase, and identify the results. This product is wireless transmission, safe, reliable, fast and accurate, adapt to a variety of phase testing occasions. Its main advantage is without the wire which connect two grids (power source) , distance up to 200M and could trough enclosure or partition plate, improve the safety, without the limitation by terrain and the structure of the equipment , easy to operate, only need one person to operate and one person to supervise.
