Abstract
A wireless communication device of the present disclosure, to which an electric power measurement value is input that is measured in an electric power measurer to which a power supply side power line and a load side power line are connected, includes a first antenna element that transmits and receives radio waves and a wireless circuit connected to the first antenna element. The first antenna element has a longitudinal side perpendicular to a line along which the power supply side power line and the load side power line extend.
Claims4
An electric power measurement device comprising:
- an electric power measurer, to which a power supply side power line and a load side power line are connected and which is configured to measure an electric power measurement value;
- and
- a wireless communication device to which the electric power measurement value is input,
- wherein the wireless communication device comprises:
- a first antenna element configured to transmit and receive radio waves;
- and
- a wireless circuit connected to the first antenna element,
- the first antenna element has a longitudinal side perpendicular to an extension direction of the power supply side power line and the load side power line, and
- the first antenna element is disposed with a distance to one of the power supply side power line and the load side power line less than or equal to ½ of wavelength of the radio frequency of the wireless communication device.
