Harmonic monitoring power meters are a three-phase four-wire multifunction power meter. With the use of a modern digitized information processed chip and high precision electric energy measuring chip, this power meter will accurately measure all the commonly used electric power parameters in a three-phase power system, including three-phase-current, active power, apparent power, line frequency, voltage unbalance, voltage harmonic, current harmonic, zero-sequence current, and other parameters.

Basic Controls’ harmonic monitoring power meter has an RS85 digital communication interface and electric energy pulse output. With its high cost performance, it easily replaces regular measuring indicators, power meters, and related auxiliary units. can take the place of regular measuring indicator, power meter and the related auxiliary units.

Application
As a smart digital front-end acquisition unit in power system, harmonic monitoring power meters are widely used in a variety of control systems, SCADA systems, energy management systems, power transformation automation, distribution network automation, community electrical power monitoring and controlling, industrial automation, intelligent building, intelligent distribution board and switch cabinets.

Moreover, harmonic monitoring power meters are field programmable to set the input parameters. Group-net communication with PLC, frequency converter and industrial control computer is accessible.
