    Product Introduction
    ETCR9500C-016 Three-Channel 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.The instrument uses 3 secondary low-voltage current pliers (diameter Φ16mm) to test the low-voltage circuit at the same time, which can directly determine the corresponding phase relationship between the high-voltage terminal and the low-voltage terminal, without multiple clamp tests.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.
    ETCR9500C-016 Three-Channel Wireless High Voltage CT Turn Ratio Tester consists of primary current pliers (high-voltage detector), secondary current pliers (3 pcs), host, high-voltage insulating rod, monitoring software, communication line, etc., The high-voltage current pliers are made of high-performance permalloy, and the test accuracy is high.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. Three secondary low-voltage current pliers are used to test the low-voltage circuit at the same time, which can directly determine the corresponding phase relationship between the high-voltage terminal and the low-voltage terminal, without multiple clamp tests.
    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.
