Energoforma 3.3-120M

Energoforma 3.3-120M

Source of AC current and voltage

Three-phase programmable current and voltage (phantom power) source

Purpose

The Source generates a single- or three-phase system of currents and voltages according to a user-specified model of signals used for accuracy testing of instruments measuring electrical energy values. 

As part of the MTS ME Test System, the Source is suitable for testing a variety of energy meters.

Application

As part of a portable test system of MTS ME series, in conjunction with reference instruments such as Energomonitor 3.3T1 or Energomonitor 3.1KM, Energoforma 3.3-120M can be applied for testing:
Conventional and smart energy meters (including meters with power quality measurement function according to IEC 61000-4-30)
Instruments measuring electrical energy values with a nominal frequency of 400 Hz including on-board devices
Power quality analysers (IEC 61000-4-30, class A and S measurements)
Measuring converters
