Power Quality Analyzer, Harmonic Meter

Product Description

1. Product Feature

The product LCD 3 phase Intelligent Multifunction Harmonic Wave Meter is adopted industrial-grade

microprocessor as the core, adopted modern digital signal processing technology, integrated functions of

electricity quantity telesignalling, telemetry, remote control and transmitter, etc into one. It is designed directly

against primary return circuit, can accomplish monitoring function of primary return circuit. It is widely used in

industry, commerce, civilian power system and substations.

The product is equipped with high-definition, large-screen, dot LCD system, which can simultaneously display

data, characters and recorded wave graphics. The man-machine interface is more simple and better to

understand.Groups parameters such as Voltage, current, power, frequency, electric energy, harmonics, switch

status,etc. can be displayed in real-time on the panel. Set parameter includes setting system parameters,

communication parameters and analog parameters, etc. All these can be set through the panel. Data are stored in nonvolatile memory and would not be lost even on power-off. And the data may be reserved more than 10 years. With highly reliable industry standard design, adopted varieties of isolation and anti-jamming

measures, the meter can reliably run in high interference power system environments.
