ZC-650 wireless relay protection vector analyzer is a distributed wireless and synchronous measurement of volt-ampere phase electrical parameters. It consists of two handheld measurement terminals. When each handheld terminal is used alone, it can be used as a three-phase volt-ampere phase meter. . When two units are used at the same time, they can simultaneously measure the parameters of six voltages, six currents' amplitude, phase and other parameters. The synchronous measurement phase error is within 0.5°, which is very suitable for transformer differential protection vector analysis and bus differential protection vector analysis.
ZC-650 wireless relay protection vector analyzer completely solves the problem of distributed synchronous measurement in the substation. It does not need GPS, no need to put the cable to introduce the reference voltage, and avoid the PT secondary short circuit caused by cable insulation or operation problems. It is simple, practical, and applicable. In situations where there is no reference voltage, such as 2/3 wiring bus protection screen, outdoor current transformer terminal box, intelligent substation merging unit front differential protection CT signal, etc., greatly improve the multi-interval phasor measurement efficiency of the whole station.
The wireless relay protection vector analyzer is also called six-phase protection loop vector tester and loop vector analyzer.
A single host can complete high-precision measurement of electrical parameters such as three-phase voltage, current, phase, frequency, power, power factor, and three-phase unbalance.
ZC-650 wireless relay protection vector analyzer has the following functions and features:
