Measure the transformer load current, load loss, short-circuit voltage, short circuit (load) losses, capability. Note: need to equip with three phase regulator yourself if need to do transformer load no-load test
Three Methods
Do three-phase transformer no-load, load test, the instrument can automatically determine the wiring is correct, and shows three-phase voltage and current vector map. Single machine can do the following 100KVA distribution transformer full load current experiment; in one third of the rated current, complete 250KVA distribution transformer load the following test (in one third of the rated current, the instrument can be converted to load loss under rated current parameters, the machine is mainly used in the test bed with integrated supporting the use of transformers. All the related test results are automatically corrected. Instrument can automatically such as: the waveform correction, temperature correction, non-rated voltage correction, calibration, and other non-rated current correction, so that more accurate test results. 320x240 large screen, high brightness LCD display, full Chinese menu and operations to achieve prompt and friendly man-machine dialogue, touch buttons make the operation more convenient, wide LCD with brightness adjustment, can be adapted to the various summer and winter season. Comes with real-time clock, automatically recording test date, time, the preservation of favorable results, management. Panel-type thermal printer, the scene quickly print test results. Data (test sample set, the measurement results, the test of time, etc.) with power-down storage and browsing features, you can store 500 set of experimental results with computer on-line data transfer. Allows an external voltage transformer and current transformer for extended range of measurement, any measurable parameter is the test product.
