CBA.306B
About the CBA.306B:
-
CBA.306B Circuit Breaker Tester is designed to
meet the needs of onsite testing the dynamic
characteristics of High-Voltage Circuit Breakers.
-
Providing a convenient dynamic analysis of various
circuit breakers and can accurately measure the
mechanical dynamic characteristic parameters of
high-voltage circuit breakers for various voltage
levels such as low oil, high oil, vacuum, SF6, etc.
-
High-voltage circuit breakers have dual tasks of
control and protection in the power system, and the
quality of their performance is directly related to the
safe operation of the power system.
-
Mechanical characteristic parameters are one of
the most important parameters for indicating the
performance of circuit breakers.
