    Product Introduction
    ETCR9570 Multifunctional High/Low 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 and secondary current size, variable ratio, angle difference, phase difference and polarity judgment of current transformers below 35kV.The instrument can also measure the voltage, current, leakage current, phase, frequency, active power, reactive power, power factor, harmonics and other power parameters of the power system, and can also display the waveforms of voltage and current, the harmonic content of the AC signal and the waveform distortion rate.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 Multifunctional High/Low Voltage CT Turn Ratio Tester consists of a handheld terminal, a small current clamp, a flexible current clamp, a high-voltage current clamp, a test line, a high-voltage insulating rod, and a host computer software. The high-voltage current clamp is made of high-performance permalloy and has high test accuracy.The handheld terminal adopts a 5-inch touch color screen and a Chinese interface, and all test results are displayed on the same screen.The high-voltage pliers have a unique automatic plug-in structure, which can easily clamp or evacuate the wire under test by pressing or withdrawing the insulating rod, and the operation is safe, time-saving and fast.The flexible current clamp is lightweight and small, suitable for places with small spaces (such as busbars in power distribution cabinets, etc.).The instrument has two measurement modes, wired or wireless, which can cope with various test sites, and the transmission distance of the wireless test mode is up to 40 meters.The insulating rod is lightweight, has the characteristics of moisture-proof, high temperature resistance, impact resistance, bending resistance, and high insulation, and 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. It has perfect functions and can measure the variable ratio of high and low voltage current transformers.It can also measure the voltage, current, leakage current, phase, frequency, active power, reactive power, power factor, harmonics and other power parameters of the power system.
    2. Automatically calculate the variable ratio, variable ratio error and angle difference of the current transformer.
    3. Analyze and measure the harmonics and distortion rates of voltage and current within 31 times.
    4. Display voltage and current waveforms.
    5. There are two measurement modes, wired and wireless, which can easily cope with various measurement occasions.
    6. The handheld terminal adopts a 5-inch TFT touch color screen with a Chinese interface and a clear and beautiful display.
    7. GPS synchronization is timed to ensure synchronization and record the longitude and latitude of the measurement location.
    8. Configuration management analysis software, running in the WINDOWS operating system, friendly interface, with graphics and curve analysis functions, convenient data management.
    9. Storage function, 2000 sets of data are stored, and the shutdown data is not lost.
    10. USB communication interface.
    11. Bluetooth communication.
    12. Rechargeable lithium battery.
