Evaluation of Voltage Transformers’ Accuracy in Harmonic and Interharmonic Measurement
The measurement of Power Quality (PQ), generally performed at Low Voltage (LV) level, is gaining more and more importance also at the Medium Voltage (MV) level, due to the increasing presence of switching power converters (both loads or generators ...

Analysis of Reactive Power in Electrical Networks Supplying Nonlinear Fast-Varying Loads
This study concerns problems related to the assessment of reactive power in power networks with nonlinear fast-varying loads, such as electric arc furnaces, rolling mill drives, etc. The operation of this type of load is characterized by the introduction

Effect of Ripple Control on Induction Motors
One method for the remote management of electrical equipment is ripple control (RC), based on the injection of voltage interharmonics into the power network to transmit information.

Analytical Frameworks and Theories of Electric Power in Non‐Linear Circuits
Based on the challenges of distorted currents and non‐linear components in modern power grids, this article reviews seminal electrical power theories that seek to generalize the traditional definitions of active, reactive, and apparent power. It provides a detailed analysis of their mathematical foundations, practical implementation, and validity.
