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 1000KVA distribution
transformer full load current experiment; in one third of the rated
current, complete 2500KVA 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 English
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 which 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 groups 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.
