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...
What are the Protection function of Active Harmonic Filter? The protection functions of an Active Harmonic Filter (AHF) are critical for ensuring its safe operation, preventing damage, and maintaining the integrity of both the AHF and the electrical system it is connected to. These protection features safeguard the AHF from various electrical faults and environmental factors. Below are the key pro...
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...
TDD vs. THD: An In-depth Analysis and Comparison Total Harmonic Distortion (THD) and Total Demand Distortion (TDD) are critical parameters that help monitor and control the level of harmonics present in electrical systems. While they both measure harmonic distortion, there are critical differences between them that engineers and technicians need to understand. THD: Total Harmonic Distortion...
With the growing adoption of energy-efficient technologies, electronics have become integral to modern power systems. Switched Mode Power Supplies (SMPS) in office equipment and LED lighting, Variable Frequency/Speed Drives (VF/SDs) for induction motors, and inverters that convert DC power from photovoltaic cells to Mains Frequency AC are prime examples of how these systems enhance power usage eff...
