ZC-820 high voltage phase tester Brief introduction



High voltage phasing tester 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, 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 use wireless transmission technology, safe, reliable, fast and accurate.
