## Understanding Asymmetrical Fault Analysis in Power Systems

Introduction Fault analysis is a crucial aspect of power system engineering, essential for designing protection systems and ensuring the reliability of electrical networks. While symmetrical faults are easier to analyze, asymmetrical faults are more common in real-world scenarios. This article delves into the concept of asymmetrical fault analysis and provides an interactive calculator for students

## Introduction to PID Controllers

A PID controller, standing for Proportional-Integral-Derivative controller, is a fundamental control loop feedback mechanism widely used in industrial control systems. A PID controller continuously calculates an error value as the difference between a desired setpoint and a measured process variable, and applies a correction based on proportional, integral, and derivative terms, hence the name. Proportional

## An Overview of Modbus Protocol

Overview of Modbus Protocol  Modbus Protocol is a widely used communication protocol in the field of industrial automation. Developed in the late 1970s by Modicon (now Schneider Electric), it was designed to enable communication between programmable logic controllers (PLCs) and other industrial devices such as sensors, actuators, and human-machine interfaces (HMIs). Despite being over four

## Nuclear Energy: Does It Worth the Risk?

As our planet continues to grapple with an ever-increasing demand for energy, the quest for cleaner and more efficient sources has taken center stage. One such energy source, nuclear power, has been a point of heated debate since its inception. The pros and cons, costs and benefits, and potential applications of nuclear energy are heavily

## Working Principle of MOSFET

A Metal-Oxide-Semiconductor Field-Effect Transistor, or MOSFET, is one of the most widely used types of transistors in modern electronics. It’s a three-terminal semiconductor device that can be used either as a switch or an amplifier. Understanding how MOSFETs work and their characteristics is vital for anyone working with electronics. In this blog, we will break

## Battle of the Energies: Solar Energy vs. Wind Energy

Introduction With the increasing availability of renewable energy sources, it can be difficult to determine which is the most efficient and cost-effective option. Solar and wind energy are two of the most commonly used sources of renewable energy available today. In recent years, their popularity has skyrocketed due to their clean, green credentials as well

## Electricity Grid Resilience: A Review

What is Electricity Grid Resilience Electricity grid resilience is the ability of the power system to withstand, absorb, and recover from any form of disruption. This includes disruptions caused by extreme weather events, cyber-attacks, natural disasters, human error, and aging infrastructure. Resilience is essential for reliable electricity delivery and a secure energy future. The electric

## The difference between active and passive filters

Any electronic system has its own frequency bandwidth (limit to the highest frequency of the signal), and the frequency characteristics reflect the essential characteristics of the electronic system. The filter is an engineering application circuit designed according to circuit parameters’ influence on the circuit’s frequency bandwidth. Everyone knows that there are many filters, and the easiest way
