Product Introduction

ETCR9620B Wireless 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 and variable ratio of the first and second circuits of the medium and low-voltage current transformers in the metering device without power failure, 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. The flexible current clamp adopts wireless transmission method, with a transmission distance of 100 meters, which is more convenient to use.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. Primary current clamp. Flexible current clamp is particularly suitable for test sites with small spaces and dense wiring. It adopts wireless transmission method with a transmission distance of 100 meters.
3 Storage function, storing 3000 sets of data.
