    Product Introduction
    ETCR9620 Low Voltage CT Turn Ratio Tester, also known as transformer current variable ratio tester, transformer ratio difference tester, and current transformer variable ratio tester, is used to test the current, variable ratio, and angle difference of the first and second circuits of the medium and low-voltage current transformers in the metering device without power-off, and judge the polarity and phase difference.The tester consists of a host, a primary flexible current clamp, and a secondary current clamp. The flexible current clamp is particularly suitable for test sites with small spaces and dense wiring.It provides a new type of power instrument that is safe, accurate and convenient for electricity inspectors.
    1. The current clamp is made of high-performance permalloy, adopts magnetic shielding and CT digital integration technology, has strong anti-interference, high accuracy and stable testing.
    2. The use of flexible current pliers for primary current pliers is particularly suitable for test sites with small spaces and dense wiring.
    3. Storage function, storing 3000 sets of data.
