Smart Electricity is quickly developing as the results of advancements in sensor technology. The accuracy of a sensing device is the backbone of every measurement and the fundamental of every electrical quantity measurement is the voltage and current sensing. The sensor calibration in the context of this research means the marking or scaling of the voltage sensor so that it can present accurate...

A comparison of the Josephson array voltage standards of the Bureau International des Poids et Mesures (BIPM) and the Physikalisch-Technische Bundesanstalt (PTB), Braunschweig, Germany, was carried out in October 2014 at the level of 10 V. For this exercise, options A and B of the BIPM.EM-K10.b comparison protocol were applied. Option B required the BIPM to provide a reference voltage for measu...

Voltage sensing technology is crucial in realizing distributed voltage at critical nodes of the power grid and providing key state variables to provide information support for control decisions. Among existing measurement methods, transformers have problems such as high insulation performance requirements limited installation locations. However, non-contact sensors designed based on electric fi...

For the results presented in my thesis the I-V data was recorded by hand based on measurements taken using hand-held DMMs. This method was slow and made it tedious to record more than a handful of data points. To improve upon this, a software controlled measurement and recording method was developed using LabVIEW and a USB connected data acquisition card (DAQ). Within this method two techniques...
