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 to do power factor correction?Introduction to Power Factor Correction: Importance and Design The growing integration of photovoltaic (PV) systems into the grid has created challenges for utility providers. One of the primary concerns is that many power electronics used in these systems consume reactive power, leading to a low power factor and system instability. As a result, power factor corre...
I. INTRODUCTION The name power quality has become one of the most productive concepts in the power industry since late 1980s. Power quality is the “Degree to which both the utilization and delivery of electric power affects the performance of electrical equipment”.Power quality is decided by magnitude of voltage and frequency. Voltage quality problem is divided into under voltage, over...
Understanding the Importance of Temperature Testing for Electrical Devices What is temperature testing, and why is it important for electrical systems? Electrical systems need to withstand a wide range of temperatures to function properly. Temperature testing is an essential part of the electrical engineering process. Temperature testing helps engineers identify potential design proble...
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...
Dynamic Voltage Restorer: The Guardian of Power Systems In modern industrial and commercial applications, maintaining power quality is crucial for the reliable operation of sensitive equipment. One of the major challenges in power quality is voltage sags and dips, which can disrupt operations and cause equipment malfunction. Enter the Dynamic Voltage Restorer (DVR) – a critical piece of equi...
Introduction Harmonics in power systems have become a significant concern due to the widespread use of semiconductor-based loads, such as variable frequency drives (VFDs) and line-commutated DC drive systems. These harmonics can lead to various power quality issues, affecting both equipment performance and system reliability. Harmonics are integer multiples of the fundamental frequency. For exampl...
What are the relationship of Active Harmonic Filter, capacitor banks and reactors? Active Harmonic Filters (AHFs), capacitor banks, and reactors are essential components used in electrical networks to manage power quality, reactive power compensation, and harmonic mitigation. When these devices are combined effectively in a network, they can help improve system performance, energy efficiency, and ...
