Micro-ohmmeters for contact resistance measurement of medium and high voltage circuit breakers.
Circuit breaker coil analyzers capable of minimum voltage test and power sources for coils and mechanisms.
Used for circuit breaker contact timing measurements, motion parameters, voltage recording, resistance measurement, and other analog signals.
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:
The 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.
