CBA-II circuit breaker test instrument is designed to meet the need of testing high_voltage switches .
It takes the micro controller unit(MCU) for core to sample, process and then output; the main characteristic is that it’s operated in english, for example ,the results are displayed and printed in English.
It has many advantages such as intelligence, multi-function, accurate data, strong anti-jamming, easy operation, small size, beautiful appearance, etc;
This Circuil Breaker Test Instrument can test the switches as follows:indoors or outdoors switches with less oil or more oil,vacuum switches, SF6 switches and so on.
