Open Delta Connection is a method of transformer connection used to transform three-phase power using two single-phase transformers. In this article, you will learn how this connection is done and the theory behind this. The Scott connection is another method …
If a person receives an electric shock, it is the utmost duty of the observer to rescue the person. The first step is to disconnect the person immediately from the live supply mains by either switching off the main switch. …
What is a switching station? A switching station is a substation that does not contain power transformers and therefore does not change system voltage from one level to another. Switching stations usually operate at sub-transmission or transmission voltage levels. Depending …
This is the complete guide to learn electrical engineering basics in 2019. The study of electrical engineering involves the analysis of the energy transfer from one form to another or from one point to another. So before beginning the actual …
In this article, you will learn different types of substation bus configuration and their application. The equipment and buses installed in the substation switchyard are arranged and connected in specific ways to form bus configurations. The industry has developed several …
This article covers transformer impedance testing, one of the acceptances tests for new transformers, and a method for routine testing. The results of this test should compare directly to the manufacturer’s datasheet. Related: Percentage Impedance of Transformer Application of Transformer …
Transformer bushing types are categorized based on their material, manufacturing, and design mainly into the following types: OIP (Oil-Impregnated Paper) Bushing RIP (Resin Impregnated Paper) Bushing RIS (Resin Impregnated Synthetic) Bushing Resin Bonded Paper (RBP) Bushing Cast Epoxy Bushing You …
A ground fault circuit interrupter (GFCI or GFI) is an inexpensive electrical switchgear device that can either be installed in your electrical system or built into a power cord to protect you from severe electrical shocks. Electric shocks can cause severe …
The goal of the auto reclosing in power lines is to restore the line to service as quickly as possible after a temporary fault in the transmission line. Automatic reclosing can be done as a three pole auto reclosing or …
