Properly analyzing power system clearing times is vital in determining what the actual hazards are. These clearing times are measured in cycles or milliseconds. Many arc flash hazard analysis are done using the relay curve of a protective device when the actual clearing time of the circuit involves many more devices such as CT's, interposing relays and circuit breaker action. This actual clearing...
The Hall effect can be employed to obtain an output proportional to the product of the current through the element and the field cutting through it. A qualitative explanation aids in the visualization of the phenomena. There are several semiconductor materials that may be selected to emphasize a particular characteristic such as power transfer, temperature stability, etc. Maximum efficiency and improvement...
