Megger Group Ltd.
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.

IBEKO Power AB
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.

CAT Standard Series -
IBEKO Power AB
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.

IBEKO Power AB
DV Power has released a new generation of circuit breaker test equipment for condition assessment of medium and high voltage circuit breakers.Field-portable instruments with standalone or PC controlled functionality, allow performing various tests during circuit breaker manufacturing, commissioning and maintenance stages.Applications supported by the DV Power test equipment include measurements of:Contact resistanceDRM (dynamic resistance measurement)Coil resistance and coil current (IEC 62271-100)Mechanism charging time (IEC 62271-100)Minimum trip voltage (IEC 56, ANSI C37.09)Undervoltage release (IEC 60694)The timing of a circuit breaker’s main, auxiliary and pre-insertion contactsSynchronization between the contactsMotion and velocity“First trip” testThe essential part of a circuit breaker condition assessment is the ability to compare the latest test results with the previous testing. Accordingly, our instruments store measured values and compare them to a manufacturer’s limits. Also, a fingerprint obtained in this way can be used at a later stage as a reference during subsequent measurements. In order to obtain an accurate comparison, the tests need to be performed using identical test parameters. Consequently, any deviation and change in the test results may indicate the circuit breaker condition deterioration. Even more, to overcome this issue, DV-Win enables test plans and graph overlay features.Finally, as a final result of a circuit breaker maintenance process, the DV-Win provides analytical tools and customized report creations.
