Four Quadrant Meter

[j.jo]

Abstract:

The Multifunction Programmable Panel Power Meter is powerful, four-quadrant programmable energy meter that features a bright LED display, two freely configurable analog outputs and serial communication ports (RS-232 and RS-485). The four quadrant meter can be programmed either through software or the push buttons on the front panel. It can be configured as a 1, 2 or 3 element device with transformer rated inputs of 5A and up to 550V.


Programmable transformer ratios allow the meter to show primary values on the display and read through the serial ports. The analog outputs can be assigned to any instantaneous quantity. Standard analog output is 20mA but this can be changed to 10Vdc with the flip of a dip-switch Quantities measured by the four quadrant meter include current, voltage, active, reactive and apparent power,powerfactor,linefrequencyandenergy.
THD indication is also available for voltage and current with individual harmonic measurements available for the 3rd through the 15th harmonics.

dear sir
i need to make a project related to 3 phase energy meter.
and as explained by you it is having a four quadrant operation
and does it display harmonic currents separately ?
and what kind of component i need if i am making this project ?
does it measure power on fundamental cycle or measure it (V.I) method ?
