Abstract

The invention relates to an electric energy quality monitoring terminal which comprises a device power supply, an input signal transformation unit, an electric energy quality detecting unit, an electric energy measurement detecting unit and a network server interface unit. The technical scheme has the advantages that the electric energy quality monitoring terminal serves the functions of an electric energy quality analyzer and an electric energy measurement detecting device; a user can conveniently measure two parameters through carrying a device; and the electric energy quality detecting unit and the electric energy measurement detecting unit commonly use the identical device power supply and the network server interface unit, so that the manufacture cost of the device is saved.

Description

【Technical field】 [0001] The invention relates to the field of power electronics, in particular to a power quality monitoring terminal. 【Background technique】 [0002] my country's electric power enterprises play a very important role in the development of the national economy. With the development of society, the quality of electric energy has been paid more and more attention. As the core instrument for verifying power quality, the power quality analyzer is an indispensable equipment in the work of testing power quality. Whether the working status of the power quality analyzer is normal is one of the issues that need to be focused on in power quality testing. [0003] Electric energy metering and testing equipment is used to detect the usage of electricity in the power grid within a certain period of time, and is one of the most commonly used equipment in the field of power systems. [0004] The above two devices are common devices in the electric power field, and are use...
