Abstract

A polyphase electricity meter comprising a metering system allowing to measure a flow of electricity through a plurality of phases of a portion of an electricity network. The electricity meter further comprises a rechargeable powering system allowing to power at least the metering system. The rechargeable powering system is charged by at least one phase of the electricity network.

Claims

1. A polyphase electricity meter comprising:

a metering system allowing to measure a flow of electricity through a plurality of phases of a portion of an electricity network, wherein the electricity meter further includes a rechargeable powering system allowing to power at least the metering system, the rechargeable powering system being charged by at least one phase of the electricity network.

2. The polyphase electricity meter according to claim 1, wherein the rechargeable powering system is charged by a single phase of the electricity network.

3. The polyphase electricity meter according to claim 1, wherein the metering system allows to measure the flow of electricity through three phases of the portion of the electricity network.

4. The polyphase electricity meter according to claim 2, wherein the metering system allows measuring the flow of electricity through a single phase of the portion of the electricity network.

5. The polyphase electricity meter according to claim 1, wherein the rechargeable powering system includes a rechargeable battery.

6. The polyphase electricity meter according to claim 1, wherein the rechargeable powering system includes a super-capacitor.
