Understanding IEEE 519-2022 Standard for Harmonic Distortion The IEEE 519 standard sets the criteria for voltage and current harmonic distortion in electrical systems. The recent IEEE 519-2022 edition, which replaces the 2014 edition as of December 2022, introduces significant changes that impact the design and management of electrical installations. Key Changes in IEEE 519-2022 &nbs...
India's power distribution companies Discoms are responsible for the supply and distribution of energy to a variety of consumers (industrial, commercial, agriculture, domestic, etc.). This is also, according to the Brooking Institute, the weakest link in the power ecosystem from both a financial and operational sustainability perspective. The quality of power quality Of course, the provision of po...
General Reference – Power Quality Assessment Procedure Abstract: Power quality is a frequently used term that means different things to different people. Common power quality problems occur because of the mismatch between a utility's power and the customer's energy-using equipment, leading to faulty operation. Some common power issues are sudden changes in voltage, electrical d...
ABSTRACT Distribution network operators face increasing challenges related to Power Quality (PQ). EDP Distribuição in Portugal has developed a comprehensive PQ monitoring program to address these challenges. This paper outlines the state-of-the-art PQ monitoring platform and methodology used by EDP, and presents results from monitoring HV/MV and MV/LV substations. Improvement actions...
Energy Efficiency and static var generator Energy Efficiency and Static Var Generator (SVG) are closely linked, as SVGs play a crucial role in improving the overall energy efficiency of electrical systems. Here’s how they are connected: 1. Power Factor Improvement: Static Var Generator SVG helps in maintaining a high power factor by providing reactive power compensation. A higher power facto...
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...
What is Motor Testing? Electrical maintenance programs are designed to enhance equipment reliability and uptime while reducing operational costs. Electric Motor Testing is often one of the first areas to be scaled back when cutting expenses. However, savvy companies recognize that neglecting proper maintenance programs can result in billions of dollars in lost revenue due to increased motor repair...
Harmonic Distortion Optimize Power with Active Harmonic Filters Introduction to Non-Linear Loads and Harmonic Distortion Non-linear loads, particularly in industrial and commercial settings, are significant contributors to electrical power quality issues. A prime example of a non-linear load is the Switch-Mode Power Supply (SMPS), which is prevalent in most digital electronic equipme...
