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