Electricity meter capable of minimizing the risk of data destruction from lightning or surge
First Claim
1. An electricity meter comprising:
- a meter housing;
a measurement part physically accommodated in the meter housing and including a detection unit which detects electricity consumption of an objective system, and a transmission unit which wirelessly transmits data representative of the detected electricity consumption;
an operation part physically accommodated in the meter housing, adjacent to the measurement part, and including a reception unit which receives the wirelessly transmitted data and an operation unit which processes the received data into data representative of electric energy consumed by the objective system; and
an insulation part physically accommodated in the meter housing and formed between the measurement part and the operation part in order to electrically insulate the measurement part and operation part from each other,wherein the measurement part and the operation part are mounted on a single printed board accommodated in the meter housing, and the data transmitted from the transmission unit of the measurement part is in the form of a radio signal.

Abstract
An electricity meter capable of minimizing a risk of data destruction in case of lightning or surge that involves improperly high voltage is provided. The electricity meter includes a measurement part, an operation part, and an insulation part. The measurement part includes a detection unit to detect electricity consumption of an objective system and a transmission unit to wirelessly transmit data representative of the detected electricity consumption. The operation part includes a reception unit to receive the wirelessly transmitted data and an operation unit to process the received data into data representative of electric energy consumed by the objective system. The insulation part electrically insulates the measurement part and operation part from each other.
