Transformer Resistance Tester

Udeyraj Electricals Private Limited offers Transformer Resistance Tester, Series TRT-27. The series TRT-27 is a high precision new generation, light weight large output current and micro-processor controlled tester. This replaces old DC wheat stone bridge and double arm bridge for measurement of DC resistance. Series TRT-27 adopts advanced test current power supply technology, four terminal measurement, digital display of resistance value and test current and are powered by 220 V AC mains single phase supply.

The measurements are accurate as the test current is highly stable. High automation is achieved with automatic discharge warning. The constant current generated is fed to the resistance under test through the current terminals and the voltage drop across the resistance under test is measured and displayed in ohms. A true four terminal measurement is used to eliminate the need for lead resistance compensation. Features: constant current source; saves 255 test results in memory; and built-in printer.

The advantages of TRT-27: quick speed measurement of resistance; high precision of class 0.2, good repetitiveness; digital display-of resistance and test current; automatic discharge and discharge warning; true 4 terminal measurement no lead compensation required; saves 255 test results; built-in printer; and light weight.
