1)Capable of doing test for CT, PT, CVT and Z-transformer.
2)complete three phase ratio test within 11 seconds.
During the manufacture of power transformer and before its
commissioning, it is required to test the turns ratio or voltage
ratio of transformer according to the requirements of preventive
test instructions of State Ministry of electric power. BBC-VI
tester, overcoming the disadvantages of the traditional ones,
adopting big LCD, easy-operating, can do the three phase ratio test
at one time and with the features of rapid test, high accuracy, and
perfect protection functions.
1, Pay attention to read this instruction carefully before usage.
2, The operator should learn well the general knowledge of
appliance or instrument.
3, Be connected to the ground firmly.
4, The input power supply is AC220V± 10%.
5, The output voltage is 160V and do prevent from electric shock.
6, The instrument can be used in or out of door but it should avoid
to be used in the vile environment of rain, corrupt gas, heavy
dust, high temperature, direct sunlight and so on.
7, No violent vibration of meter.
