How Ground Fault Protection Works
... sense any loss of current. If the current flowing through the circuit differs by a small amount from that returning, the GFCI quickly switches off power to that circuit. The GFCI interrupts power faster than a blink of an eye to prevent a lethal dose of electricity. You may receive a painful shock, ...

Motor Protection Voltage Unbalance and Single
... From the above data, it can be seen that 44% of motor failure problems are related to HEAT. Allowing a motor to reach and operate at a temperature 10°C above its maximum temperature rating will reduce the motor’s expected life by 50%. Operating at 10°C above this, the motor’s life will be reduced ag ...

... 1831, some 12 years after Oersted’s discovery, the English scientist Michael Faraday (1791–1862) and the American scientist Joseph Henry (1797–1878) independently demonstrated that magnetic fields can produce currents. The basic process of generating emfs (electromotive force) and, hence, currents w ...

Synchronous Generator Load Angle Measurement and Estimation
... conditions not exceeding the range of allowable loading. The exceeding of allowable loading would cause the activation of generator protection and disconnection of a synchronous generator from an AC system. This could cause (depending on the state of an AC system) disconnection of other aggregates f ...
