Générateurs d'impulsions d'étalonnage conformes à la norme IEC60270
Le générateur d'impulsions d'étalonnage standard CAL1A couvre la gamme de 1/2/5/10/20/50/100 pC, tandis que le CAL1B, destiné principalement aux tests de machines tournantes, couvre la gamme de 0,1/0,2/0,5/1/2/5/10 nC.
For transformer testing Power Diagnostix offers four different models: CAL1C, CAL1D, CAL1G, CAL1J; all of them beeing suitable for laboratory and online tests. The CAL1C comes with an external capacitor 100 pF, whereas a switchable external capacitor 100pF/1nF is included in the delivery range of a CAL1J.
Power Diagnostix delivers the calibrators of the CAL1 series with a fully traceable DAkkS calibration that is done on the basis of the method mentioned in the IEC60270-2000 A.3. This calibration certificate guarantees that the deviation of the charge output from its nominal value is less than 0.2 pC + 0.02 × q, with 'q' beeing the displayed value.
To ensure a reliable PD measurement, all calibrators shall be calibrated annually; the calibrator is re-adjusted, if necessary, and outfitted with a new battery.
