Abstract

The invention relates to an electricity metering system, an electricity measuring device and an electricity metering device. The electricity measuring device measures power factors, a current effective value and current harmonic content of a power transmission line and sends the power factors, the current effective value and the current harmonic content of the power transmission line to the electricity metering device in a wireless mode; the electricity metering device measures a voltage effective value of the line and receives the power factors, the current effective value and the current harmonic content of the power transmission line from the electricity measuring device; the loaded electricity of the power transmission line is calculated according to the power factors, the current effective value and the voltage effective value.

Description

technical field [0001] The invention relates to a power metering system, a power measuring device and a power metering device, and belongs to the field of electric power metering. Background technique [0002] At present, with the continuous increase of social power consumption load, the requirements for power supply reliability are also constantly improving. As the last link of power supply to users, the operation status of power distribution equipment directly affects the quality of power supply to users. Because power distribution equipment The quantity is large, the distribution area is wide and scattered, and limited by personnel, measuring equipment and quantity, it is usually only necessary to measure the electricity consumption of a few or dozens of users. The easiest way is to measure the 10-35KV transmission lines at the input ends of these users power. The traditional metering method is to use high-voltage voltage transformers, current transformers, arresters to ...
