Handheld Circuit Breaker Analyser

Handheld Circuit Breaker Analyser – Overview

The Handheld Circuit Breaker Analyser is ideal for use when it’s not practical to use a conventional robust circuit breaker. It is specially designed for testing circuit breakers with one break per phase. Their compact and ergonomic design can provide a wide range of features and reliable operations in low, medium, and high-voltage substations or in industrial environments. It consists of two models, the CAT-P and CAT-H. Both have a large (5,7 in) coloured touch-screen display. Test results are visible in dark places as well as in bright sunlight. The Li-Ion battery can last up to 8 hours of testing without recharging. It records: main contacts operating times, contact synchronisation, sequence time, a resistance of pre-insertion resistors, open and close coil currents, main contacts bounce time, auxiliary contact time, and DC Voltage. Multiple operations, such as Open-Close and Open-Close-Open, can be initiated by using a predefined delay time or by triggering a signal from current clamps connected to the circuit breaker coil. CAT-H is capable of performing coil control, while this feature is optional for the CAT-P. In contrast to CAT-H, the CAT-P instrument can execute the “First Trip” test. Both instruments display numerical and graphical results. A user can easily overlay up to 4 records in the graphical form and make a quick on-site analysis of potential defects. Test results can be downloaded to a PC via Bluetooth interface for more detailed analysis using DV-Win software.
