Product Introduction

ETCR9500B Wireless High Voltage CT Turn Ratio Tester, also known as transformer current variable ratio tester, transformer ratio difference tester, current transformer variable ratio tester, is used for primary current, secondary current size, variable ratio, phase difference, polarity judgment of current transformers below 35kV.It is widely used in substations, power plants, power inspection departments, industrial and mining enterprises, testing stations, electrician maintenance departments for current detection, anti-theft and field electrician operations.
ETCR9500B Wireless High Voltage CT Turn Ratio Tester consists of a primary current clamp (high-voltage detector), a secondary current clamp, a host, a high-voltage insulating rod, monitoring software, and a communication line. The high-voltage current clamp is made of high-performance permalloy and has high test accuracy.The high-voltage current clamp has a unique automatic plug-in structure. It can easily clamp or evacuate the wire under test by pressing or withdrawing the insulating rod. The operation is safe, time-saving and fast. The insulating rod is lightweight and has the characteristics of moisture-proof, high temperature resistance, impact resistance, bending resistance, and high insulation. The insulation level is 110kV.The instrument has a storage function, a USB communication interface, and the stored data can be uploaded to a computer for historical data reading, viewing, saving, printing, etc.
1. The high-voltage current clamp is made of high-performance permalloy material, which has strong anti-interference and high test accuracy.
2. The innovative automatic plug-in and unplugging structure of the high-voltage current clamp can easily clamp or evacuate the wire under test by pressing or withdrawing the insulating rod, which is safe, time-saving and fast.
3. The high-voltage current clamp adopts wireless transmission method, with a transmission distance of 100m.
4. Storage function, storing 3000 sets of data.
5. USB communication interface.
