NRRL-H laboratory standard transformer capacity & loss tester is researched and developed by our company, it is a high precision instrument developed specifically for transformer capacity and loss parameter measurements. It can test the transformer capacity, type, no-load current, no-load loss, short circuit (load) loss, resistance voltage, etc.
Overview
Characteristics
3.1 It can measure the capacity of various distribution transformer and electric transformer on site without additional power supply so the test is more convenient and faster;3.2 It can measure no-load current no-load loss impedance voltage load loss and other transformer characteristic data of various transformers in combination with external power supply and voltage regulating voltage boosting current raising and other equipment;
3.3 All test results are automatically corrected. You only need to input the relevant parameters (such as temperature no-load correction factor etc.) the instrument can automatically carry out correction such as waveform distortion correction temperature correction non-rated voltage correction non-rated current correction etc. so as to improve the accuracy of test results.;
3.4 In the measurement of transformer characteristics the maximum voltage range can reach 750V the maximum current range can reach 100A and the internal protection circuit is equipped. When measuring it is not necessary to switch gears to ensure measurement accuracy and it is not necessary to worry about burning the instrument due to wrong gear selection.;
3.5 When testing the characteristics of the transformer the voltage and current ranges can be expanded very flexibly and easily just through the external voltage transformer and current transformer which greatly widens the test range of the instrument;
3.6 Large screen high brightness liquid crystal display full English menu and operation tips realize a very friendly man-machine dialogue interface; wide temperature brightness adjustable liquid crystal screen can adapt to different environmental temperatures;
3.7 Large screen high brightness liquid crystal display full English menu and operation tips realize a very friendly man-machine dialogue interface; wide temperature brightness adjustable liquid crystal screen can adapt to different environmental temperatures.
