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.

Primary Injection Test Systems
Primary current injection testing is utilised in high current/high voltage scenarios found at large electrical installations such as substations. A large current (between 100A and 20,000A depending on system specifications and test requirements) is injected directly on the primary side of the electrical system such as a circuit breaker. The objective of the test is to identify how the system operates under various levels of current load.

Analyzers and Timers
CAT Advanced Series
Description The Advanced CAT Series Analyzers and Timers are stand-alone or PC-controlled digital instruments for circuit breaker status evaluation. Timing channels record arc closing and opening, resistance and auxiliary contacts. The main contact channels can also measure the resistance value of pre-insertion resistors (if present in the breaker). The advanced CAT series records graphs of the opening and closing coil currents and the movements of the moving parts of the high and medium voltage circuit breaker. Test results are printed on the 112 mm (4.4 inch) thermal printer (optional accessory) in tabular and graphical form. The advanced CAT series provides easy selection of different operating modes:

Transformer Rectifier Assemblies
Transformer rectifier assemblies are very useful in OEM applications when unregulated DC output is required. Input power can be single-phase or three phases. With single-phase input power, the output ripple is 50%. With three-phase input power, the output ripple is 5%. A 5% output ripple is a clear advantage. Hence, transformer rectifier assemblies with three-phase input power are more popular. Circuit breakers, fuses, voltmeters, and ammeters can be added per customer requirements. The assemblies can be an open frame or inside an indoor enclosure.

Voltage Detectors
JSC-88AW
The JSC-88AW is a very reliable way to know for sure whether or not there is voltage downstream from the switches or breakers during power-offs. It dramatically increases the safety of personnel assigned to maintenance work on electrical equipment powered by three-phase voltage. As long as voltage is present downstream of the breakers, one or more (LEDs) of the JSC-88AW will stay lit. A simple visual inspection tells you whether the electrical system is in “Zero Energy” mode. In addition, this new device has been improved to enable resistance to voltage spikes (transients).
