High voltage dc circuit breakers
WebThe circuit breaker ratings most commonly referred to are voltage, frequency, frame, continuous current, short-time current, short-circuit current, fuse, control voltage, and megavolt ampere (MVA) ratings. Figure 1. It is important to ensure that circuit breakers are properly applied within their ratings as specified on the circuit breaker ... WebWhen a high current or voltage is interrupted, an arc is generated. The length of the arc is generally proportional to the voltage while the intensity (or heat) is proportional to the current. This arc must be contained, cooled and extinguished in a controlled way, so that the gap between the contacts can again withstand the voltage in the circuit.
