TRM 50 TRM 50+ Transformer Winding Resistance Meter The most advanced Transformer Winding Resistance Meter injects up to 50A DC ... ...TRM 50

TRM 50 / TRM 50+ The Product TRM 50 / TRM 50+ : Advanced Transformer Winding Resistance Meter SCOPE introduces 50A state of the art precision winding resistance meter, specially designed for field testing as well as factory testing of large transformers up to 500MVA. Winding resistance value of transformer and rotating machine are directly displayed on 5.7” TFT display. TRM 50 is designed to work in live EHV switchyard conditions, ensuring operator’s safety and repeatability of results. Maintenance time saving is ensured by one time connection to transformer with simultaneous resistance...

SCOPE CTrans Software Powerful and user friendly CTrans software controls the Instrument when used in control through external PC / Laptop mode. With CTrancs all the tests can be carried through laptop. WRT (Winding Resistance Test): This test can be selected to measure the resistance of connected phases. In case of TRM 50+ user can connect all the phases of primary as well as secondary at a time and in case of TRM 50 either all phases of primary or secondary can be connected at a time. In this test, the current is stabilized in the winding and instruments reads resistance of each winding...

ATWRT (All Taps Winding Resistance Test): The instrument has facility to operate the OLTC. Special feature of measurement of winding resistance of all the taps, automatically recording the results and generating single report is provided in this test. If user selects the Raise cycle, the tap is brought to first tap position. The current in the winding is stabilized and resistance of first tap is measured and stored. Then instrument operates the OLTC for Raise operation and reads the second value. Thus resistances of all the taps are measured and displayed in tabulated form. Same test can be...

SCOPE For OLTC test: This is the laptop operated feature. In this test the variation in the DC current flowing through the winding during tap change is sampled and plotted against time. The graphs of entire Raise or Lower cycle are captured and results of each operation are stored and presented in tabular form in report. User can select either Raise or Lower cycle. If the Raise cycle is selected, the tap is first brought to first position. Then current is stabilized in the winding. TRM operates the OLTC for Raise operation and waits for drop in current during contact changeover. This drop...
