‘Three Phase Power Energy Meter Calibrator’ Model ZM3ØPEC is a source of AC Voltage, AC Current, Power Factor, frequency, time. Thereby it is also a source of VA, VAr, W, VAhr, VArhr, and Whr.

It has 6 different sine wave signals which are synchronized with each other. Three of them are amplified and controlled as per set values to get phase to neutral voltages of three phases which are 120˚ phase shifted with each other.

Other three sine wave signals are amplified and controlled as per set values to get currents of three phases which are 120˚ phase shifted with each other.
