Circuit Breaker Analyzer & Timer CAT34 is a standalone or a PC-controlled digital instrument for condition assessment of the circuit breakers. It is intended for testing timing and travel on circuit breakers with one break per phase.
The timing channels records closing and opening of the main, resistor, and auxiliary contacts. CAT34 records graphs of both the open and close coil currents and displacements of the HV and MV circuit breaker moving parts.
Viewing and overlaying several graphs for complete and easy test result comparison. Selecting the measurement points and intervals using two available cursors. Zoom and pan graph feature. Specific test sequence setup. Customized configuration of test result graphs.
For the CAT form of DV-Win software there is Help menu available, with detailed instructions and explanations of all functions and features.
