Three Phase Power / Energy Meter Calibrators / Watt Meter Calibrators

Three Phase Power / Energy Meter Calibrators / Watt Meter Calibrators
Three Phase Power / Energy Meter Calibrator

We are Manufacturer, Supplier, Exporter of Three Phase Power / Energy Meter Calibrator. This product also known as Watt Meter Calibrator, Energy Meter Calibrator. We are also specialized in Calibration Services & our setup is situated in Pune, Maharashtra, India.

Three Phase Power Energy Meter Calibrator 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 120o 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. To simulate power factor user can vary the phase shifts between the sets of voltages and currents by 2 push button keys provided so as to set lead and lag PF. By varying potentiometer of set frequency user can set the frequency. Time can be set on timer by thumbwheel switches. At any given instance timer can be switched on and the output currents are switched OFF after the lapse of the programmed time.


Features
