Abstract (en)
[origin: GB2426596A] An electricity meter for measuring the amount of electrical energy supplied by an electrical power supplier to an electrical power consumer via an electrical power distribution circuit consisting of at least two electrical supply leads and a safety lead. The meter comprises a current sensor for sensing the current flowing in at least one of the electrical supply leads, and a voltage sensor for sensing the voltage across a measurement load and an energy sensor responsive to the current and voltage sensors. The meter is provided with an internal power supply whereby the measurement circuitry can remain actively powered in the event of a fraud where the voltage sensor is disabled, such that current measurement can take place and whereby relative measurement of power can be determined by use of a representative voltage value.
