ES1010 wireless high and low voltage ratio ratio tester is also called high and low voltage CT wireless ratio tester. It is composed of high voltage detector, low voltage current clamp, main engine, high voltage insulation rod, monitoring software and communication line. The instrument adopts fast digital circuit processing technology. In the case of not disconnecting the line at the scene and uninterrupted power, connecting insulating rods to measure high voltage current transformers up to 60kV, primary of transformers, high-voltage primary currents, low-voltage secondary currents, and can calculate the ratio of change, phase, polarity, and ratio error.
When not using insulation rods, they can also be used as high-precision low-voltage clamp ammeters and leakage current meters. It is easy to use and portable. Its wireless transmission function can receive measured data within 30 meters of a straight line, ensuring high-precision, high reliability, and high stability throughout the year. The host uses a large-screen LCD display, featuring small size, light weight, and portability. It can store 500 data sets. High-voltage current measurement range of 0.0mA ~ 1200A, low-voltage current measurement range of 0.0mA ~ 20A.
High-voltage detector current signal using wireless transmission technology, connecting the insulation rod, by pushing or withdrawing the insulation rod, it is easy to clamp or withdraw the measured wire, saving time and fast. It can be widely used in substations, power plants, industrial and mining enterprises and testing stations, electrical maintenance departments for current detection and field electrical work. Insulation rods have characteristics of light weight, moisture resistance, high temperature resistance, impact resistance, bending resistance, high insulation, etc.
