Transformer Direct Resistance Meter

I. Key Features

l All high and low voltage current potential test wires are connected to the transformer at once, eliminating the need to reroute test wires during the testing process.

l For the star connection winding test, the instrument can adopt a three-phase simultaneous testing method.A0、B0、C0The phase resistance, saving testing time.

l During the low-voltage testing of a transformer with three-phase, five-column internal corner connection, the instrument employs an automatic magnetizing method, which is faster than using high currents directly.

l Present all test data for the high and low voltage windings of display and printing transformers, automatically calculate the three-phase unbalance, and print the resistance values converted to the rated temperature.

l During the three-phase test, the initial testing is conducted.A0Our data shows that simultaneous three-phase testing has resolved the issue of not being able to test the neutral point lead resistance during simultaneous three-phase tests, resulting in test data that is closer to single-phase test values.

l Comprehensive reverse voltage protection features.

l The instrument's interior canForever.LongStorage Test Data200Line (expandable), and can also use a USB drive to store data for easy import and processing on computers.

l The instrument features a wide operating temperature range, high precision, shock resistance, anti-interference capabilities, and easy portability.
