ISA CBA1000
Description
CBA 1000is a unique tool for the complete test of all circuit breakers. It is a powerful timing and motion analyzer test set with a built-in 200 A pure DC current micro Ohm meter for static and dynamic contact resistance tests.
CBA 1000measures 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 1000 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 pre-define test plans. TDMS is also a powerful Test and Data Management software, compatible with all ISA Test Sets.
All CBA 1000 circuits have been designed to ensure safe and reliable operations in the noisy environment of HV / MV substations and power plants.
