INMEL 8033 Calibrator is a three-phase electric power and energy calibrator. It generates voltages of equal rms value on three voltage outputs and currents of equal rms value on three current outputs. The voltage on voltage output and the current on current output are shifted between them by set phase angle. Against to the previous model calibrator type INMEL 33, the new device INMEL 8033 one characterize less voltage, current, power and angle generation error, has also wider frequency range of quantity generate and richer program function set. The most important from program functions is the possibility to generate harmonic course. The main distinctive feature of INMEL 33 from INMEL 8033 is digital method measurement generating and stabilization output signals. Application: Checking ang calibration: - Wattmeters, varmeters, - phase meters, - frequency meters, - AC of voltmeters and ammeters, - power factor and phase angle meters, - measuring transducers, - watt-hour meters in single and three-phase system, - power engineering protections.
