Introduction:

This DC resistance tester, also known as transformer DC resistance tester, is an important instrument to check whether the connection or mechanical characteristics between windings, windings and leads are good, and whether the resistance between each phase winding is balanced, so as to ensure the safe operation of the transformer.

Transformer DC resistance tester is a new type of instrument suitable for measuring the DC resistance of large-capacity transformer.

It is designed as a high-precision current-stabilized power supply and test module.

During the test process, it is controlled by a computer and automatically completes the steady state judgment, data acquisition, data processing and resistance measurement. Value display and printing.

This instrument can be used for longitudinal test of on-load voltage regulator with secondary power supply, which completely saves test time. It also has the temperature rise test function of the transformer manufacturer.

It has the characteristics of simple operation, high accuracy and anti-interference, and can measure various types of transformers quickly and accurately. The magnetic aid method is to charge the low winding by generating a magnetic field for the output current of the high winding.

With the help of the excitation ampere turns of the high voltage winding, the winding inductance is greatly reduced by passing a small current to shorten the measurement time and achieve the purpose of rapid measurement.

It should be noted that when measuring the DC resistance of low voltage winding with magnetic aid method, the current direction of high and low voltage winding on the same iron core column must be the same, so as to play the role of magnetic aid.

This DC resistance tester is composed of host, test line, etc. It has the functions of reading, consulting, saving and printing historical data
