Circuit Breaker Analyzers & Timers
-
CAT circuit breaker analyzers and timers are advanced standalone or a PC controlled instruments for circuit breaker maintenance. Typical application areas of CAT instruments are medium and high voltage substations at electric power generation, transmission, and factories of switchgear. Also, industrial environments and electric power distribution are suitable application areas for these circuit breaker testing instruments.DV Power CAT circuit breaker testing instruments are portable and lightweight. They are designed for performing mechanical operations intended for circuit breakers testing according to standards IEC 62271-100 and IEEE C37.09.These instruments measure:the timing of main contacts, pre-insertion resistor contacts, auxiliary contacts operations,coil currents,motion parameters,voltage recording,main circuit resistance,arcing contacts wipe,and any relevant analog signal.Motion transducer channels provide measuring a displacement of the circuit breaker moving parts, contact wipe, over-travel, rebound, damping time, and average velocity. Even more, CAT circuit breaker analyzer optionally has a built-in micro-ohmmeter. Hence, it provides the main circuit resistance measurement and dynamic resistance measurement. Dynamic resistance measurement is an effective method for arcing contacts condition assessment.

Tracer Gas Leak Test Systems
-
Tracer gas leak testing is a simple and highly-efficient method of leak detection that provides high sensitivity as well as increased accuracy and repeatability. This method is used for testing parts with very low leak rates that are outside the range for conventional air-flow pressure decay and mass flow, or to replace bubble test methods. Tracer gas testing uses escaping tracer gas to identify micro-leaks in the range of 1x10-4 to 10-9 scc/s.
