                             Q96-WTCZA Q72-WTCZA Q144-WTCZA Three phase wattmeter

Overview

Q96-WTCZA Q72-WTCZA Q144-WTCZA Three phase wattmeter is specially designed for the power monitoring system of industrial and mining enterprises, civil buildings, building automation and other industries. The instrument adopts AC sampling technology and sets CT and Pt parameters through panel keys, which can visually display the primary side electric flow of three-phase AC system. The meter is equipped with RS485 communication interface and can be compatible with various configuration systems through standard Modbus protocol, so as to transmit the electric energy collected by the front end to the system data center in real time.

Working principle

Q96-WTCZA Q72-WTCZA Q144-WTCZA Three phase wattmeter --- use the pointer to indicate the instantaneous value of active power consumed by the current equipment. P active watt hour meter - the dial indicates the cumulative value of active power consumed by the current equipment. Measure the active power measured by w (w = PT) active power meter. It is different from the value of total power obtained by connecting an AC voltmeter and an AC ammeter in series on the load. It must be less than or equal to the value of total power. This ratio is called power factor, The total power measured by V meter and a meter minus the active power measured by active power meter is the reactive power value on the current line. For example, you string a few UF capacitors in a 220V circuit (the withstand voltage should exceed。
