Idling (electrical engineering)
In electrical engineering, idling is the state in which no electrical consumer is connected to an electrical voltage source (or a power generation unit ) or is operated in the switched-on state. In this case, no electrical current flows and the open circuit voltage of the voltage source reaches its maximum value.
The opposite of electrical no-load operation is the electrical short-circuit of a voltage source, in which the current reaches a maximum value through a virtually resistance-free electrical conductor bridge as long as the voltage is still provided by the power generator. The electrical voltage at the output is approximately zero.
This is to be distinguished from the operation of electrical machines which, although they consume power, do not perform any mechanical work other than their own internal movement , i.e. are operated in idle mode on the output side . The current that flows for this operating case is called the no-load current, the power consumed by the machine is called the no-load loss. This performance is lower than when operating at full or partial load .
