BIL or Basic Insulation Level Definition Table and Calculation

Basic Insulation Level Definition When lightning impulse over voltage appears in the system, it is discharged through surge protecting devices before the equipments of the system gets damaged. Hence, the insulation of such equipment must be designed to withstand a certain minimum voltage before the

Electrical Transmission Tower: Types, Design & Parts

What is a Transmission Tower? A transmission tower (also known as a power transmission tower, power tower, or electricity pylon) is a tall structure (usually a steel lattice tower) used to support an overhead power line. In electrical grids, they are used to carry high voltage transmission lines tha

Inductance in Transmission Line

Reason of Transmission Line Inductance Generally, electric power is transmitted through the transmission line with AC high voltage and current . High valued alternating current while flowing through the conductor sets up magnetic flux of high strength with alternating nature. This high valued altern

Flexible AC Transmission Systems | FACTS

Flexible AC Transmission Systems (FACTS) – What and why? FACTS is the acronym for “Flexible AC Transmission Systems” and refers to a group of resources used to overcome certain limitations in the static and dynamic transmission capacity of electrical networks. The IEEE defines FACTS as alternating c

Equal Area Criterion

At first we have to know about power stability study. Stability study is the procedure for deciding the stability of a system upon some disturbances and this is followed by several switching actions (ON and OFF). In the power system , the behavior of synchronous machine can have some impacts due to

Corona Discharge: How to Reduce The Corona Effect

Corona Discharge , also referred to as the Corona Effect, is an electrical discharge phenomenon that occurs when a conductor carrying high voltage ionizes the surrounding fluid, often air. The corona effect will occur in high-voltage systems unless sufficient care is taken to limit the strength of t
