DC resistance tester is an ideal piece of equipment for measuring transformer windings and large power output inductor equipment

◆ typical four-wire system measurement, more precise when measuring resistance values, especially that of low resistance
◆ The central control unit imposes a constant and precise current to an external load which is to be measured

General Introduction

When the transformer is cross-connected, overhauled or some of its switches are changed, direct current resistance testing of the transformer winding is a must. In general, to measure the transformer winding or large power output inductor equipment, the traditional electrical bridge method and pressure drop method require much time and energy. Thus, our company developed rapid direct current resistance detector, which is designed with new power supply technology and possesses the characters of small in volume, easy to operate and precise in result. Transformer DC resistance tester is an ideal piece of equipment for measuring transformer windings and large power output inductor equipment.

DC resistancet tester accords the national standard of GB6587-86, i.e. the General Program for Electronic Measurement Equipment Environment Test and GB6593-86, i.e. the Rules for Quality Verification of Electronic Equipment.


Structure Characteristics

DC resistance tester operates on the typical four-wire system measurement, in order to be more precise when measuring resistance values, especially that of low resistance. The main body of a testing electric circuit consists of a program controlled constant current source, a program controlled optical preamplifier and an A/D converter. The central control unit imposes a constant and precise current to an external load which is to be measured, after analyzing the data acquired (including testing voltage, current testing current and so on), you can get the real resistance value.

DC resistance tester can save 255 testing data, which will not lose when it is reset or out of electricity. All the data saved can be printed.
