Test Your Circuit Breaker in the Quickest Possible Way - Less Than 20 Seconds!

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 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.

Features:

• Lightweight (only 1,6 kg / 3.5 lbs) Handheld Circuit Breaker Analyzer and Timer CAT-H with its compact and ergonomic design can provide a wide range of tests:
•  Main arcing contacts operating time and bounce time measurement with pre-trigger time feature
•  Timing and resistance measurement of the pre-insertion resistors (if present in the Circuit Breaker)
•  Auxiliary contact operating time measurement
•  Close and Trip coils current measurement with numerical values and corresponding graphics
• Voltage measurement and condition of substation power source
• Test results can be downloaded from CAT-H to PC

CAT-H is a battery-operated (up to 8 hours), handheld measuring device with 5.7 in touch screen color display and with internal memory storage - over 30 000 test results. The instrument displays numerical and graphical results (it can overlay up to 4 records in graphical form or compare 2 test results in numerical form with pre-defined limits) which enables quick onsite analysis of potential defects by comparing the obtained test results.
