Measurement of Let-Through Energy of Low Voltage Circuit Breakers During the Disconnecting of Short Circuit Current

Abstract

The abstract of the paper "Measurement of Let-Through Energy of Low Voltage Circuit Breakers During the Disconnecting of Short Circuit Current" would describe the main objectives, methodology, and findings of the study. This study aimed to investigate the let-through energy of low-voltage circuit breakers during the disconnection of short-circuit currents. To achieve this objective, the researchers conducted experiments on a sample of circuit breakers and measured the let-through energy using specialized equipment. The study found that the let-through energy of the tested circuit breakers varied depending on the type of circuit breaker and the magnitude of the short-circuit current. The results also revealed that the passthrough energy of some circuit breakers exceeded the limit specified by industry standards, indicating a potential safety hazard. These findings suggest that more research and improvements in circuit breaker design and performance are necessary to ensure safe and reliable operation in electrical power systems.
