192x95x55mm Double Clamp Transformer Testing Equipment

RS20000B Double Clamp Digital Phase Meter is special designed for testing voltage, current and phase onsite, it is in high-precision, low price, portable hand-held, dual-channel input measuring products. It’s easy to measure the phase between U-U, I-I and U-I, identify the inductive circuit ,capacitive circuit and the phase sequence of three-phase voltage, detect the wiring group of transformer, test the secondary circuit and bus differential protection system, read the phase relationship among the CT groups of a differential protection system, and check if the watthour meter was correctly wired. When testing customers do not need cut off the measured circuit which input by split core current transformer. When measuring the phase between U1 and U2, the two input circuit loop are completely insulated isolation, so the possibility of misconnection is absolutely avoided, which may result in short circuit or even burn the meter. The device with high-contrast LCD screen, and the character in big size, which helps to obtain the best visual effects

Product Features

1. 1. Withstand Voltage

   Parts between voltage input terminal and meter shell, parts between the iron core of the clamp-current transformer and secondary windings can stand 1000V/50Hz. Parts between the two voltage input terminals can stand Sinusoidal AC Voltage 500V/50Hz for 1min when testing.

   2. Insulation Resistance

   Between meter circuit and meter shell, between the two voltage input terminals:≥10MΩ
