Technical Method for Traceability Achievement of DC Voltage Measurements up to 5 kV at NIS, Egypt

This paper describes a technical method for achievement of traceability in DC voltage measurements starting from 10 mV up to 5 kV at National Institute of Standards. Traceable calibration of Fluke 5720A Calibrator, up to 1 kV, has been performed. To extend the traceability for the value of 5 kV, a universal high voltage divider has been used. All calibrations in this technique have been conducted using a Fluke 732B Zener Diode Reference Standard, which is traceable to SI units via the DC Voltage Primary Standard (JVS) of NIS. The relevant results, with emphasis on the uncertainty budgets, are presented.
