The voltage coefficient of compressed gas capacitors is a relevant parameter in high-voltage calibrations. These capacitors, used as standards, are calibrated at low voltages so that it is necessary to know their variation when they are used at high

Very fast transient overvoltages appear when switches operate in high voltage networks. In some cases, they can affect near current transformers (CT). In this paper, a new methodology for measuring these transients is proposed. It uses the stray capa

The objective of this work is to study the uncertainty associated with the measurement of energy losses in a distribution network. It is done by means of differences between input and output energies of each region. For this, the energy measurement s

Smart grids need, among other requirements, to reduce out-of-service periods as much as possible. This leads to carefully planned equipment maintenance-working, for which it is necessary to use many tools. An important one is the voltage detector. Th

This paper details the development of the design of a very high accuracy calibration system for voltage transformers based on a current comparator. It digitizes the signals by high precision DMMs, and then those signals are reconstructed. The modulus

With the advance of renewable generation in power systems, a new measurement problem arises. Wind and solar plants inject energy to the power network most of the time, but during some periods, as in the night or during low wind, they consume. The met

A set of resistive voltage dividers was designed to be used in a measuring system of electric power up to 100 kHz. The calibration of the dividers based on the step-up method and a comparison system based on two Keysight-3458 digital multimeters work

We present a summary of the results of an intercomparison of high voltage capacitance between the National Metrology Institutes of Argentina (INTI) and Uruguay (UTE). The traveling standard was a 400 kV, 50 pF capacitor, SF6-isolated. This capacitor
