Switchgear is a critical component of any electrical system, ranging from small-scale residential setups to large industrial plants. It helps control, protect, and isolate electrical equipment, ensuring the safety, reliability, and efficiency of power distribution. In this article, we will explore t
The magnetic circuit is an important component of the transformer core, which is a laminated or wound structure that provides a low magnetic resistance path for the main magnetic flux generated by the excitation winding. A part of the iron core is surrounded by windings, called the iron core column;
1. Fuction:When lightning overvoltage invades a substation or other buildings along an overhead line, flashover may occur, and even the insulation of electrical equipment may be punctured. Therefore, if a protective device, namely a surge arrester, is connected in parallel at the power inlet end of
A transformer is mainly composed of the core, windings, oil tank, conservator, bushings, tap-changer, breather, pressure-relief device, radiator, Buchholz (gas) relay, oil purifier, and internal insulation. Their functions are described below:1. CoreFunction: Forms the magnetic circuit for alternat
