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.

First Trip Testing of Circuit Breakers
-
Significance of Circuit Breaker "First Trip Time"A circuit breaker may not be called upon to operate and clear a fault for years, but when a fault occurs, it is expected to operate within it's published time-current characteristics. Unfortunately, frequently this does not happen... environmental contaminants, hardened grease, vibration and other factors can adversely affect the operating time of the circuit breaker.

The sophisticated design ensures efficient and reliable operations in high-voltage substations and industrial environments.The CAT Advanced series are stand-alone or PC-controlled digital instruments for a circuit breaker testing. The timing channels record closing and an opening of the arcing, resistor, and auxiliary contacts. Also, the main contact channels can measure the resistance value of the pre-insertion resistors (if present in the circuit breaker).With CAT Advanced series instruments, it is possible to record graphs of open and close coil currents. Furthermore, it records displacements of the HV and MV circuit breaker moving parts. Test results can be saved via USB, PC or be printed via 112 mm (4.4 inches) thermal printer (optional accessory) in tabular and graphical form.A circuit breaker test consists of different operational modes and CAT Advanced series supports:Open (O)Close (C)Reclose (O-0,3s-C)Trip free (CO)O-0,3s-COOpen-Close (O-C)Close-Open (C-O)Open-Close-Open (O-C-O)First trip (O)Multiple operations, such as Open-Close and Open-Close-Open, can be initiated by using a predefined delay time or by sensing a breaker’s contact position.The auxiliary inputs are used to monitor dry and wet auxiliary contacts. The six coil control analog channels measure and record coil currents simultaneously (OPEN and CLOSE), up to 35 A AC/DC.The additional six voltage analog channels have four selectable voltage ranges available (±1 V, ±5 V, ±60 V and ±300 V AC/DC).A built-in micro-ohmmeter generates up to 500A true DC ripple-free current with an automatically regulated test ramp that provides performing static and dynamic contact resistance measurement.Three transducer channels provide a measuring displacement of the circuit breaker moving parts, contact wipe, over-travel, rebound, damping time and average velocity. Also, a user can connect either an analog or a digital transducer to these universal channels.

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.

Circuit Breaker Analysis Systems
-
When a fault such as a short circuit or current overload is detected by a protective relay, a trip impulse is sent to the circuit breaker. The circuit breaker must function as specified and interrupt the current as soon as possible or severe damage may occur. The damage caused by a malfunctioning circuit breaker can often be catastrophic, resulting in significant damage to the electrical system.
