The CAT Series of circuit breaker analysers and timers are standalone or PC controlled digital instruments for circuit breakers’ condition assessment. They enable simultaneous measurements of up to 12 main contacts (4 breaks per a phase) including pre-insertion resistors and 6 auxiliary contacts. These instruments record graphs of the open and close coil currents and the displacements of the HV and MV circuit breaker moving parts. The main contact channels can also measure the resistance value of any pre-insertion resistors.

The operational mode [Close (C), Open (O), Close-Open (C-O), Open-Close (O-C), Open-Close-Open (O-C-O)] is fully selectable by the user. All test results can be stored in internal memory, a USB memory stick or printed on a thermal printer in both tabular and graphical form. All CAT units are supplied with DV-Win software, which provides full instrument control alongside acquisition and analysis of test results.

DV Power provides a 3-year warranty on all test instrumentation. This is a guarantee to our customers that they will receive the highest quality test equipment on the market.

The first series of CAT circuit breaker analysers and timers have been primarily designed for timing and motion measurement of HV and MV circuit breakers.
