1. Characteristics
The wireless high and low voltage transformation ratio tester is also called high and low voltage<>The wireless transformation ratio tester consists of a high voltage detector, a low voltage current clamp, a host, a high voltage insulating rod, monitoring software, communication lines, etc. The instrument uses fast digital circuit processing technology to measure the following high-voltage current transformers, primary currents of transformers, high-voltage primary currents, low-voltage secondary currents, and The transformation ratio value, phase difference, polarity, and transformation ratio error can be calculated.
When the insulating rod is not used, it can also be used as a high-precision low-voltage clamp ammeter or leakage ammeter<> It is simple to use and easy to carry
. Its wireless transmission function can be received within a straight line<> meters The measured data ensures high precision, high reliability and high stability of uninterrupted testing all year round. The host adopts a large screen display and is small in size, light in weight and easy to carry. It can save data sets. High voltage current measurement range
.~<> Low voltage current measurement range
.~<>.
The current signal of the high-voltage detector uses wireless transmission technology to connect the retractable insulating rod. By pushing forward or withdrawing the insulating rod, it is convenient to clamp or evacuate the wire under test, saving time and speed. It can be widely used in substations, power plants, and industrial and mining enterprises. As well as testing stations and electrician maintenance departments for current testing and field electrical work. Insulating rods are lightweight, moisture-proof, high temperature resistant, impact resistant, bending resistant, highly insulating and retractable.
