What are the differences between PLC, HMI, and SCADA?
A Programmable Logic Controller, or PLC, is a rugged industrial computer designed for real-time control. It interfaces directly with sensors and actuators, executing control logic typically written in ladder logic, structured text, or function block diagrams. PLCs are built to withstand the harsh conditions...

What is Fault Current – Understanding kA Ratings in Electrical Systems
Fault current is the huge rush of electric current through a circuit in the event of a fault. The fault could be short circuit between phases, line-to-earth fault, or phase-to-neutral fault. In a fault, the resistance (or impedance) within the circuit is reduced to...

Insulation tester – What is the purpose? Explained!
An insulation tester, also called an insulation resistance tester or megohmmeter, is a specialized electrical instrument that measures how well insulation resists electrical leakage. In electrical systems, insulation surrounds conductors, cables, and equipment to prevent current from flowing along unintended paths. Effective insulation allows...
