Electrical Circuits
A complete path, or circuit, is needed before voltage can cause a current flow through resistances to perform work. There are several types of circuits, but all require the same…
Co-ordination and Discrimination of Relays
CO-ORDINATION PROCEDURE Correct overcurrent relay application requires knowledge of the fault current that can flow in each part of the network. Since large-scale tests are normally impracticable, system analysis must…
Control Circuits
Control Control, as applied to control circuits, is a broad term that means anything from a simple toggle switch to a complex system of components which may include relays, contactors,…
Types of Capacitor Bank
Unit of a capacitor bank is normally called capacitor unit. The capacitor units are manufactured as single phase unit. These single phase units are connected in star or delta to…
Mobile Substation | Portable Substation | Mobile Transformer
What is Mobile Substation? Sometimes it is required to supply power to a particular place in fully temporary basis. Such as at civil contraction or other construction places where huge…
PID Control
PID control stands for proportional plus derivative plus integral control. PID control is a feedback mechanism which is used in control system. This type of control is also termed as…
Industrial Automation
Due to the rapid advances in technology, all industrial processing systems, factories, machinery, test facilities, etc. turned from mechanization to automation. A mechanization system needs human intervention to operate the…
