A programmable logic controller or programmable controller is an industrial computer that has been ruggedized and adapted for the control of manufacturing processes

Instrumentation and control engineering (ICE) is a branch of engineering that studies the measurement and control of process variables, and the design and implementation of systems that incorporate them. Process variables include pressure, temperature, humidity, flow, pH, force and speed. ICE combines two branches of engineering.

A PLC is a hardware-based device, SCADA is a system that works in conjunction with the PLC. But, an HMI is also a system that works in conjunction with a PLC. Since the SCADA system and an HMI can complete more or less the same functions, it’s crucial that you know the difference between these two.

“Captive Power Generation” means generation of electricity exceeding 1 MW for the purpose of consumption by the generator, and which is consumed by the generator itself, and not sold to a third-party. “Captive Power Plant” means a power plant of over 1MW in capacity set-up by the generator for own use.

A power inverter, inverter or invertor is a power electronic device or circuitry that changes direct current to alternating current.

The substation is an electrical power station where the voltage level is changed by special apparatus (power transformer, and other switchgear equipment) and sent to a different location which is called a substation.
