Wireless high and low voltage 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. It can connect insulation rods to measure high-voltage current transformers , primary transformers, high-voltage primary current, low-voltage secondary current, and can be calculated under the condition of not disconnecting or powering on site. Change ratio, phase, polarity, and ratio error below 60kV
When not using the insulation rod, it can also be used as a high-precision low-voltage clamp ammeter, leakage current meter, can accurately measure the current of 0.1mA, it has the characteristics of easy to use, easy to carry.
Its wireless transmission function can receive measured data within 30 meters (without obstacles) in a straight line, ensuring high precision, high reliability, and high stability for continuous testing without interruption.
The host uses a large-screen LCD display, featuring small size, light weight, and portability. It can save 500 groups data.
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, through the push or pull back the insulation rod can easily clamp or evacuation of the measured wire, save time and fast.
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 are light, moisture-proof, high-temperature resistant, impact-resistant, bend-resistant, and highly insulating.
