Insulation Resistance Testing (Megger Test) for Transformers

Introduction Insulation resistance testing, commonly known as the Megger test, is an essential procedure for assessing the quality and reliability of electrical insulation in transformers. This test helps in detecting insulation deterioration that could eventually lead to transformer failures. It’s a non-destructive method that verifies the integrity of insulation between various transformer windings and from

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

Electric Motor Overload Protection

Electric motors are the workhorse of modern life, powering everything from the hum of your home appliances to the colossal machinery of heavy industry. Yet, like any tireless worker, they require protection from the very force that fuels their work: overcurrent. Unchecked, excessive current can lead to catastrophic consequences, jeopardizing not only the motor itself
