Overcurrent Protection and the NEC – IAEI Magazine

WebThe basic test procedure is: Open circuit the generator terminals. Drive the machine at synchronous speed using an external mechanical system. Slowly increase the field current and measure the open circuit terminal voltage. As there is no armature current, the measured terminal voltage is the induced voltage: V O C = E. Web1 de mar. de 2024 · An open circuit is defined as an electric circuit in which current does not flow. Current can only flow in a circuit if it finds a continuous path—known as a “closed circuit”. If there’s a break anywhere in the circuit, you have an open circuit, and current can not flow. In an open circuit, the two terminals are disconnected.
