2 Introduction of WB5110-D
2.1 Overview
WB5110-D Multifunctional Harmonic Meter is a multifunctional electric panel meter features with
integrated functions of programmable of measurement parameters,LED display, digital communication ,
relay measurement & control and analogue measurement.
It measures and analysis the Voltage , Current, Active Power, Reactive Power, Apparent Power, Power
Factor, Frequency, Active Energy, Reactive Energy, Four-quadrant Energy, Time-period Energy, Monthly
Energy, Harmonic Distribution (2-31 times) of voltage and current, Total harmonic distribution (THD) of
voltage and current, Unbalanced degree of current and voltage, Positive sequence current and voltage,
Negative sequence of voltage and current, Zero sequence of voltage current, Current K coefficient, Voltage
peak-coefficient, Harmonic wave-factor, etc. It also records the event of Maximum (minimum) value,
lacking phase / over voltage and programming etc.
WB5110-D has four plug-in modules for optional functions to select; they are Analogue Input, Relay Input,
Analogue Output and Energy Pulse Output.
WB5110-D may a direct substitute of conventional indication instrument, energy meter and harmonic
measuring meter. As a front sampling element of advanced smart & digitalized electric net, WB5110-D is
suitable for applications of any types of control system, energy management system, substation automation,
power distribution net automation, electric power monitoring of individual community, industrial
automation, smart building, intelligent distribution cabinet and switch board, etc.
WB5110-D is easy to be installed, wiring and maintained. And its input parameters can be programmed at
working field site.
