BKZ-SC10 Transformer DC Resistance Tester

Estimated delivery : 30 Days; MOQ : 1 PCS
Product Introduction Overview :
The DC resistance of the transformer is a must-test item for semi-finished products, finished products, factory tests, installation, overhaul, after changing the tap switch, handover tests, and preventive tests by the power department during transformer manufacturing. It can check the welding quality of the winding joints and whether there is a short circuit between turns of the winding. It can detect whether the contact of each position of the voltage tap switch is good, whether the actual position of the tap switch is consistent with the indicated position, whether the lead wire is broken, and whether there are broken strands of multi-strand wires. The instrument adopts a new power supply technology, with the characteristics of small size, light weight, large output current, good repeatability, strong anti-interference ability, and perfect protection function. The whole machine is controlled by a high-speed single-chip microcomputer, with a high degree of automation, and has automatic discharge and discharge alarm functions. The instrument has high test accuracy and easy operation, and can realize the rapid measurement of the DC resistance of the transformer.

Features :
The whole machine is controlled by a high-speed single-chip microcomputer with high automation and easy operation.
It adopts the latest power supply technology, with multiple current levels and a wide measuring range, and can automatically select the test current according to the load.
480*270 true color LCD touch screen, clear display under strong light, dual function of touch screen/button.
RS232 and USB interfaces, capable of communicating with a computer (optional) and storing data in a USB flash drive.
The protection function is perfect, which can reliably protect the instrument from the impact of reverse electromotive force, and the performance is more reliable.
With discharge sound alarm and screen prompt, the discharge indication is clear to reduce misoperation.
Fast response speed, stable measurement data, and automatic data refresh during the test.
Intelligent power management technology effectively reduces internal heating of the instrument and saves energy.
The non-power-off clock and non-power-off memory can store data permanently.
Small size, light weight, the instrument is powered by a built-in lithium battery pack, making it easy to use.
