Product Introduction:
XSN-SQ522 digital double clamp phase voltammeter is a high precision, low price, portable handheld, double channel input measuring instrument designed for field measurement of voltage, current and phase. With this table, the phase between U-U, I-I and U-I can be easily measured on site, the phase sequence of inductive circuit, capacitive circuit and three-phase voltage can be judged, the wiring group of transformer can be detected, the secondary circuit and the differential protection system can be tested, the phase relation between CT groups of differential protection can be read, and the wiring correctness of watt-hour meter can be checked. The current to be measured is input by means of a clamp current transformer, so there is no need to disconnect the measured line during measurement. When measuring the phase between U1-U2, the two input circuits are completely insulated and isolated, so it completely avoids the possible short-circuit of the measured line caused by misconnection and the burning of the measuring instrument. The display uses a high-contrast LCD screen with a screen Angle that can be freely shifted about 70° for optimal visual effects.
