Setup of standard PD calibrator and its uncertainties [PDF]

Journal of Electrical Engineering and Technology, 2011
The present paper describes the setup of standard partial discharge calibrator for measuring partial discharge and estimating uncertainties. The standard PD calibrator was designed and set up, consisting of a digital pulse generator, capacitor modules, and a digital oscilloscope controlled by software developed in the laboratory.

LONG-TERM STABILITY OF Co-C AND Pd-C EUTECTIC FIXED POINTS FOR THERMOCOUPLES CALIBRATION [PDF]

Measuring Equipment and Metrology, 2021
Eutectic fixed points are close to becoming a reference for high temperatures calibration, especially as the new International Temperature Scale (ITS) approach to issue after the re-definition of the Kelvin unit. In this work the long-term stability of Co-C and Pd-C eutectic fixed points were investigated using NIS-Egypt facilities.

Uncertainty assessment on the calibration of Pt/Pd thermocouples at the freezing point of copper

Proceedings of the 41st SICE Annual Conference. SICE 2002., 2003
For uncertainty assessment on the calibration of Pt/Pd thermocouples at the freezing point of copper, uncertainty components of the automatic ice point for the reference junction, the digital voltmeter, the thermocouple extension wires, and the copper wires were estimated.

Comparison of partial discharge (PD) calibrators from 0.1 pC to 10 nC

Metrologia
Main text High-voltage partial discharge (PD) tests require calibration of PD measurement systems using PD calibrators which provide known values of the apparent charge. A set of travelling reference calibrators was circulated among 14 participating laboratories and each laboratory reported apparent change and rise time measured using ...
