Power tester for electric device

Abstract

The invention discloses a power tester for an electric device, comprising a voltage transformer, a current transformer, an A / D (Analog-to-Digital) conversion module, a parameter input unit, a theoretical working current conversion module, a theoretical working voltage conversion module, a current average processing module, a voltage average processing module, a timing circuit, a statistic time clearing preset key, a display unit and a controller, wherein the A / D conversion module is respectively connected with the current transformer and the voltage transformer; the timing circuit is used for counting the actual working time of a tested electric device; and the controller is used for calculating the electric power and electric consumption of the tested electric device according to average processing results of the current average processing module and the voltage average processing module by combining working time mounted by the timing circuit. The power tester is reasonable in design, convenient to install and arrange, simple and convenient in use and operation, high in intelligent degree, good in using effect and capable of effectively solving various practical problems such as lower detection precision, not high intelligent degree, incapability of directly inquiring electric consumption and the like existing in the traditional electric power testing device.

Description
