Power grids are a combined system where the electrical energy produced by the power
plants is transmitted to consumers. This forms a specific interdependence where the …

Current and voltage instrument transformers are essential elements of the power system.
They work like transformers but do not transmit power. Their task is to accurately transform …

The paper presents developed measuring system for evaluation of the transformation
accuracy of harmonics of distorted voltage by medium voltage instrument transformers …

In this paper the results of the tests of the wideband transformation accuracy of medium
voltage (MV) inductive voltage transformers (VTs) in the frequencies range from 50 Hz up to …

Overvoltage transients occur after any type of switching activity in a power network, such as
breaker operation, fault occurrence/clearance and rapid load change. This distortion of …

The current transformers with split-core are used for installation in places where it is
impossible to install classic current transformers. Moreover, this design allows for any …

Solid-state transformer (SST) is an emerging technology that integrates with transformer
power electronics converters and control. The most noticeable advantages of SST are the …

In the case of the inductive voltage transformer (VT), the resonance phenomenon may be
the main reason for its poor transformation accuracy of the non-sinusoidal voltage. This …

The design of industrial rectifier transformers for use in the field of aluminum production
