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.
Closing and opening time measurement of 12 channels
Max difference of closing or opening time measurement of three phases
Bounce time and frequency measurement of breaker closing
Circuit breaker closing and opening speed measurement
Travel-time, Coil current-time curve of circuit breaker operation measurement
Clearance of circuit breaker measurement
Variable DC circuit breaker operation power supply
Print test results by internal micro printers
