Circuit Breaker Testing is utilised to test the operation of each switching systems and the programming of the entire tripping structure. Circuit Breaker Testing is essential to ensure the safe and reliable performance of this key link in the power asset chain. Circuit breakers perform three main tasks:
Performing circuit breaker testing is more challenging with comparison to other electrical components like transformer as the short circuit current is greater. In the US market and regions of frequent earthquakes, the most popular high-voltage circuit breakers are "dead tank" units, whereas in central Europe "live tank" breakers are standard. Elsewhere both circuit breaker types are obtainable.
A circuit breaker might stay idle years, but if a malfunction occurs it has to detach fault currents of huge kiloamps gradually within a few milliseconds. Major errors that happen on circuit breakers are incorrect behavior, short circuits in the coils, damage/wear to the mechanical connections or the insulation material. Therefore, circuit breakers need to be regularly and carefully tested. Circuit breakers perform a vital role in protecting expensive equipment from damage through faults i.e. connecting and disconnecting the electrical power in a reliable way; this requires proving their reliability with on field tests during installation and with regular maintenance tests during its lifetime to prevent costly failures and problems that could even compromising the safety of the substation. Testing the performance of your circuit breakers regularly is therefore an essential and cost-effective part of any maintenance strategy. Circuit breaker testing particularly concentrates on obtaining motion and time values on the units. However, our testing solutions have revolutionized circuit breaker testing. Performing the tests without use of the station battery greatly increases safety throughout the testing process.
