Six system requirements of HV and EHV circuit breakers | EEP

Terminal Faults. Usually the short-circuit current is inductive in nature, and the re-strike voltage appearing across the contacts at the instant of arc interruption is characterized by high-frequency oscillations in the order of a few hundred cycles. Short Line Faults (SLF) Short-circuit faults occurring on a line length between 0.5 to 5 km are termed as s hort line faults or kilometric faults. A fault of this type imposes a highly onerous duty on the circuit breaker, thereby affecting its interrupting ability. Transformer Magnetizing and Reactor Currents. The transformer no-load current and the reactor current impose severe stresses on the circuit breaker upon their interruption because of the low magnitude of these inductive currents. Energization of Long Transmission Lines. When an initially uncharged, unloaded long line is charged, then over-voltages to the order of twice the normal voltage are impressed, imposing an onerous duty on the power system.

4 Critical Tests for Evaluating HV Circuit Breaker Performance

Contact Timing Test. Circuit breakers are equipped with fixed and moving contacts that are housed within an arcing chamber. The moving contacts are actuated by the operating mechanism to quickly open or close the circuit. Mechanical Motion Test. Motion tests are performed using a circuit breaker motion analyzer equipped with a transducer to check the operating mechanism stroke, velocity, damping, and over-travel against the manufacturer specifications. Control Circuit Test. A circuit breaker is only as good as the system that controls its operation. Most modern circuit breakers are equipped with electronic coils that actuate mechanisms responsible for opening and closing the main contacts. Dynamic Resistance Measurement (DRM) Contact wear is an important factor that can affect the performance of a circuit breaker. High resistance between the contacts and contact pitting are prime examples.
