Abstract
An example method of estimating an arc duration in a circuit breaker includes receiving a first measurement corresponding to a low-frequency electric field emitted from a vacuum circuit breaker during an interruption or circuit break operation and a second measurement corresponding to a low-frequency magnetic field, vibration, or acoustic emitted by the vacuum circuit breaker during operation, aligning the first measurement and the second measurement in time, wherein the first measurement is calibrated according to a first physical constant and wherein the second measurement is calibrated according to a second physical constant; and determining, by a sensor-fusion algorithm or a trained AI model, an estimated duration value of an arc duration using the time-aligned first measurement and second measurement, wherein the arc duration corresponds to a first time corresponding to a separation of contacts of the vacuum circuit breaker and a second time corresponding to arc extinction.
