Circuit Breaker Analyzers & Timers
CAT Handheld Series
When it’s not practical to use conventional robust circuit breaker analyzers, a handheld circuit breaker analyzer and timer may come handy. DV Power has developed a unique CAT Handheld series. It is specially designed for testing of 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.CAT Handheld series consists of two models, CAT-P and CAT-H. Both of them have a large (5,7 in) colored touch screen display. Because of that, test results are visible in dark places as well as in bright sunlight.Powerful internal Li-Ion battery of the instruments can last up to 8 hours of testing without recharging.CAT Handheld series records:main contacts operating times,contact synchronization,sequence time,a resistance of pre-insertion resistors,open and close coil currents,main contacts bounce time,auxiliary contact time,DC Voltage.Multiple operations, such as Open-Close and Open-Close-Open, can be initiated by using a predefined delay time or by triggering signal from current clamps connected to circuit breaker coil.CAT-H is capable of performing a coil control, while this feature is optional at CAT-P instrument. In contrast to CAT-H, CAT-P instrument can execute “First Trip” test.Both instruments display numerical and graphical results. Because of that, a user can easily overlay up to 4 records in the graphical form and make a quick on-site analysis of potential defects.A user can download test results to a PC via Bluetooth interface for more detailed analysis using DV Win software.
