ISA CBA2000
Description
The CBA 2000is a unique test set for the complete test of all circuit breakers. It is a powerful timing and motion analysis requirement with a built-in 200 A pure DC micro hm meter for static and dynamic contact resistance tests.
The CBA2000 measures CB operation times according to international standards: Open (O), Close (C), Open-Close (O-C), Close-Open (C-O), Open-Close-Open (O-C-O). It is also possible to set up customized operation sequences. In this way is possible to get the circuit breaker spread. At the same time, you can measure the coils currents.
CBA 2000 is a stand-alone unit with a large graphical display. The unit is supplied with TDMS analysis software. TDMS performs test results analysis and creates test reports; it allows also to pre-define test plans. TDMS is also a powerful Test and Data Management software compatible with all ISA Test Sets. All CBA 2000circuits have been designed to ensure safe and reliable operations in the noisy environment of EHV and HV substations.
