The ES1010 wireless high voltage ratio tester, also known as the high and low voltage CT wireless ratio tester, consists of a high voltage detector, low voltage current clamp, host, high voltage insulation rod, monitoring software, communication line, etc. The instrument adopts fast digital circuit processing technology internally, which can measure the primary, primary, and secondary currents of high-voltage current transformers and transformers below 60kV by connecting insulation rods without disconnecting wires or disconnecting power on site. It can also calculate the transformation ratio, phase, polarity, and transformation ratio error.

When not using insulating rods, it can also be used as a high-precision low-voltage clamp ammeter and leakage ammeter, which has the characteristics of simple use and easy portability Its wireless transmission function can receive the tested data within 30 meters in a straight line, ensuring high precision, reliability, and stability for uninterrupted testing all year round. The host adopts a large screen LCD display, which has the characteristics of small size, light weight, and easy portability, and can store 500 sets of data.

The measurement range for high voltage current is 0.0mA to 1200A, and the measurement range for low voltage current is 0.0mA to 20A. The current signal of the high-voltage detector adopts wireless transmission technology and is connected to a retractable insulation rod. By pushing or pulling the insulation rod forward, it is easy to clamp or withdraw the tested wire, saving time and speed It can be widely used in substations, power plants, industrial and mining enterprises, as well as testing stations and electrical maintenance departments for current detection and field electrical operations. Insulated rods have the characteristics of lightweight, moisture-proof, high temperature resistance, impact resistance, bending resistance, high insulation and stretchability.
