CAT Handheld Series

DV Power has developed a unique CAT Handheld series circuit breaker analyzer. 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.
