Introduction Power quality is a general term used to describe the compatibility between connected equipment and its electrical supply. The supply system can be affected by changes to the frequency or amplitude of the voltage, the balance between phases on a three-phase system, and distortion levels of the original signals. The characteristics that are important and what can be tolerated by the con...
Abstract Harmonic distortion in power systems is a critical challenge that electrical engineers face, especially in today's complex and technology-driven environments. The proliferation of non-linear loads—such as variable frequency drives, power electronic converters, and uninterruptible power supplies (UPS)—has led to an increase in harmonic distortions that degrade the quality of po...
Managing Non-Linear Load Harmonics with Active Power Filters Introduction Non-linear loads are becoming a significant challenge in today’s electrical systems. These loads cause the current to be non-sinusoidal, even when connected to a sinusoidal voltage source. This non-sinusoidal current contains harmonic currents that interact with the power distribution system, leading to v...
What are Even and Odd order Harmonics? Even and Odd Order Harmonics refer to the classification of harmonics in an electrical system based on their frequency in relation to the fundamental frequency. Understanding the distinction between even and odd harmonics is important for analyzing and mitigating power quality issues. 1. Harmonics Overview: Fundamental Frequency: The base frequency of th...

EcoPower Cube is the most promising solution to enable a more sustainable and environmentally friendly transportation system. Traditionally, electrical energy storage for vehicle applications has been limited to starting lighting ignition (SLI) sub-systems. However, the increase in vehicle electrification has led to the rise in the energy, power, and cycling requirements of vehicle energy storage ...
Benefits of reactive power compensation What is reactive power? Reactive power is the electrical energy used to establish and maintain a circuit's electric and magnetic fields, particularly in devices with electromagnetic coils. Reactive power is measured in VAR (volt-amperes reactive) or kVAR (kilovolt-ampere active). The formula for reactive power is: Q=V×I×sinϕ Q: reacti...
How Power Distribution Systems Work?Electrical power supplied to residential, commercial, and industrial buildings is typically generated by a utility at a centralized location and then transmitted and distributed through the utility’s power transmission and distribution system to its end users. A utility's power transmission and distribution system is responsible for controlling, pro...
