Circuit Breaker Analyzers & Timers
CAT Advanced Series
-
DV Power circuit breaker analyzer and timer utilizes the latest technological enhancements for safe and fast testing of circuit breakers. 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.

Circuit Breaker Analyzers & Timers
CAT Standard Series
-
Circuit breakers are being tested during manufacturing, commissioning or maintenance stages. The most basic test requires timing measurement using circuit breaker timer. Their primary role is timing and motion measurement of medium and high voltage circuit breakers. Devices from CAT Standard series have suitable application in:electric power generation,distribution system,part of the electric power transmission system,contractors testing,and industrial environments.CAT Standard series meets the requirements of an easy to use circuit breaker timer and analyzer with an attractive price. Furthermore, they are portable and lightweight (weighs only up to 7 kg). Finally, the plastic case is unbreakable and has IP67 protective rating when the lid is closed.CAT Standard series includes five models:Three circuit breaker timers – CAT03, CAT31, and CAT61Two circuit breaker analyzers – CAT34 and CAT64CAT03 is a basic model intended only for timing measurement of main contact operations on the circuit breaker with one break per phase. Unlike CAT03, CAT31 has the possibility of circuit breaker operation initiation, coil current measurement, and auxiliary contact timing measurement. CAT61 differs in comparison to CAT31 by its ability to measure up to two breaks per phase.CAT34 and CAT64 are more advanced compared to CAT31 and CAT61, respectively, since they have additional analog channels. Also, they have the possibility of a travel curve recording.A user can download the test results to a USB memory stick or save it to internal memory. The CAT Standard series internal memory can store up to 500 test results (numerical and graphical data). Optional thermal printer prints test results in tabular and graphical form on 80 mm (3.15 inch) paper rolls. CAT Standard series instruments are compatible with DV-Win software. It provides full control of all CAT functions from a PC, as well as acquisition and analysis of test results.

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.
