Since a battery is used for the power supply, the calibration of the ungrounded specimen can also be performed accurately.
The "NPG-3 Partial Discharge Calibrator" is a calibration charge generator used for the calibration of the entire partial discharge measurement system or the partial discharge measuring instrument itself. It generates waveforms with rise times equivalent to those of partial discharge in air and oil at a frequency of approximately 100 P.P.S. Additionally, the calibration charge can be generated arbitrarily from 0 to 2500 pC, and it can be read directly on the display. Please feel free to contact us if you have any requests. 【Features】 ■ The meter features a hybrid display of liquid crystal and digital analog. ■ It is compact, with a volume ratio of 2/3 compared to the NPG-2. *For more details, please download the PDF or feel free to contact us.
