Abstract: A switching system for an electricity meter, an electricity meter with a switch system and a method of switching switch are provided. In order to improve lifetime of the switch the timing of outputting a switching signal is adjusted based on a time difference between previously outputting the switching signal and achieving a predefined switching state.

Abstract: In the field of power distribution networks, a digital output circuit, for controlling an item of equipment within a power distribution network, comprises a switch element openable and closeable to selectively permit the flow of current to an item of equipment being controlled in use by the digital output circuit. The digital output circuit also includes a current acquisition circuit to measure the current flowing through the switch element. In addition, the digital output circuit includes a condition monitoring circuit that is arranged in communication with the current acquisition circuit. The condition monitoring circuit is configured to record the measured current flowing through the switch element as the switch element closes and thereby establish a switch element closing signature.
