3ph Reference Standard Meter

This instrument is used to measure three phase AC energy and voltage, current, power and other parameters in lab.

This instrument is used to measure three phase AC energy and voltage, current, power and other parameters in lab, and it also can be used to integrated in the energy meter test system and supply the standard energy pulse and every measurement parameters.

Structure of the instrument: stationary metal case, standard 4U, 19 inch size.

In the front panel of the instrument: pulse/communication/data interface, LCD touch display and indicator;

In the Rear panel of the instrument: voltage/current input terminals, power supply /pulse

/communication interface, power on/off switch.

This instrument is used to measure three phase energy and its parameters, the functions are described below.

Energy Measurement

Measure three phase AC energy, and output as the mode of energy accumulation pulse, digital communication, accumulated data display and etc.

Calculate the error of the reference energy pulse.

Measure AC parameters

Measure three phase AC parameters: voltage virtual value, current virtual value, active power, reactive power, PF, phase angle, frequency.

Measure voltage/current vector

Measure vector of the three phase voltage/current to its relative benchmark (normally it is Ua).

wave record and KFFT

Record wave of three phase voltage, current, and calculate the highest harmonic content of voltage, current according to KFFT.

output and input of the energy pulse

The instrument has two channels pulse output and one channel pulse input, operator can select to output high frequency active energy pulse, high frequency reactive energy pulse, low frequency active energy pulse, low frequency reactive energy pulse, and select to input active energy pulse, reactive energy pulse.

Communication and data transfer of the instrument

The instrument has two serial communication interfaces: used to receive command of the PC and output measurement data;

The instrument has one USB interface: used to upgrade the firmware of the instrument and extend function in the future.
