CBAK Power Software Module is fully loaded with user friendly options for easy
checking of circuit breaker performance analysis.
Individual profile settings of each
circuit breaker model can be
stored along with password
protection. It has separate menus
loaded with travel analysis, motor
current analysis and entire
contact timing waveform analysis.
Right side figure shows the typical
C-O operation timing waveforms
of a spring operated VCB along
with its supply DC voltage profile
variations, travel characteristics
and motor current characteristics.
Left side figure shows the typical
Close Operation timing waveforms
of a single pole magnetic actuator
operated VCB along with its close
coil current profile, travel profile
and DC voltage profile variations.
Below figure shows the Travel
results of O-C-O operation. CBAK Power software is designed to evaluate the speed and
distance travelled for each operation using automatic software mode and also manual
mode.
