Product Introduction
KGZC-1A transformer DC resistance tester is an essential test item for transformer after handover, overhaul and change of tap-changer. Under normal circumstances, it is a time-consuming and labor-intensive task to measure the DC resistance of transformer winding and high power inductance equipment by traditional methods (bridge method and voltage drop method). In order to change this situation, shorten the measurement time and reduce the workload of the tester, the company has developed a DC resistance rapid tester.
KGZC-1A transformer DC resistance tester built-in rechargeable battery and charging circuit, using high-speed A/D converter and multi-range programmable current source technology, to achieve a wide range of resistance measurement.
KGZC-1A transformer DC resistance tester has a high degree of automatic measurement function, with high accuracy, wide measuring range, stable data, good repeatability, strong anti-interference ability, perfect protection function, fast charging and discharging speed and so on.

Product Characteristics
1, high-speed 16-bit A/D converter, stable measurement data, good repeatability.
2, built-in rechargeable battery and fast charging circuit, with charging indication and overcharge protection function.
3, automatic program control current source technology, both can manually select the typical value of the output current can also be automatically controlled by the internal microcontroller output current, a total of 3000 current gear inside the current source, in the automatic state, by the internal microcontroller according to the measured resistance automatic control, so as to achieve a relatively wide measurement range and the best measurement state.
4, real-time dynamic display, fast response, can directly convert the tap-changer in the measurement state, the instrument will automatically prompt, the new resistance value will be displayed soon, no need to restart.
5, highly intelligent design, clever and advanced function Settings, can automatically judge the test line virtual connection, broken line and other faults.
6, the protection function is perfect, can reliably protect the impact of the counterpotential on the instrument, with automatic discharge indicator function.
7, can display the measurement current and measurement time.
8, can store 250 measurement data, power failure is not lost.
9, all Chinese menu and operation prompts, intuitive and convenient.
