ETCR EM9600 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 large-caliber current clamp, and a secondary current clamp.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 primary current clamp uses a large-caliber current clamp, which is suitable for various test environments, and on-site testing is convenient and fast.
3. Storage function
