While the Smart Circuit Breaker works with a mechanical contactor, the Smart Hybrid Circuit Breaker integrates both mechanical and semiconductor elements for even faster protection. The Smart Solid State Circuit Breaker is a pure semiconductor switch. All actively measure voltage and current directly at the switching element.
They provide important protection against overload, short circuits, and leakage. However, the increasing complexity of modern environments means regular circuit breakers may not meet all emerging demands. Distributed energy resources, more sophisticated controls, and heightened safety standards are increasingly important.
Over/Under-Voltage Protection: Smart breakers can detect voltage levels that are too high or too low and take appropriate action to prevent damage to electrical equipment. Over/Under-Frequency Protection: They monitor the frequency of the electrical supply and can interrupt power if the frequency deviates from the set parameters.
The paper performed an analytical study based on the circuit breaker operation in the high voltage direct current application to highlight the technological improvement and circuit topologies. A comparative analysis towards different types of circuit breakers to achieve efficient fault current isolation is presented.
Open-Phase Protection: This feature detects a missing or open phase in the system, which can lead to equipment malfunction or damage. Electrical Parameter Measurement: Smart breakers can measure and monitor various electrical parameters such as current, voltage, power, and energy consumption.
