MEWOI1570 multifunctional high and low voltage CT transformation ratio tester is a power testing product carefully designed by our company. It is mainly used for online measurement of primary current, secondary current, transformation ratio, ratio difference, Angle difference, phase/polarity judgment. This instrument can also measure power parameters such as voltage, current, leakage current, phase, frequency, active power, reactive power, power factor, and harmonics of the power system. It can also display voltage and current waveforms. The harmonics of AC signals contain rate and waveform distortion rate.
This instrument is composed of handheld terminal, small current clamp, flexible current clamp, high voltage current clamp, test line, high voltage insulation rod, PC software and so on. The handheld terminal adopts a 5-inch touch color screen, all test results are displayed on the same screen, and the operation is convenient. It has a USB interface to upload the test records to the computer. It has a Bluetooth communication function, and the measurement results can be viewed on the mobile phone. The primary current is measured with flexible current clamps or high-voltage current clamps, and the secondary current is measured with high-precision small current clamps. Flexible current clamps are especially suitable for low-voltage busbars and other places where large current clamps are inconvenient to clamp. High-voltage current clamps can be connected to insulating rods for current measurement of high-voltage lines below 60kV. High-voltage current clamps have a unique automatic plug-in structure. By pressing or withdrawing the insulating rods, it is convenient to clamp or evacuate the tested wires to ensure the safety of operators. . The instrument has two measurement modes, wired or wireless, which can be used in various test sites, and the transmission distance of the wireless test mode is up to 40 meters.
MEWOI1570 multifunctional high and low voltage CT transformation ratio tester can not only be used for transformation ratio measurement, phase measurement and power measurement, but also can be used as clamp ammeter, clamp power meter, high voltage clamp ammeter, and can be widely used in substations. Power plants, power inspection departments, industrial and mining enterprises, inspection stations, and electrical maintenance departments conduct current detection, anti-stealing electricity, and field electrical work.
