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 Impedance Test The Transformer Impedance Test locates problems within the transformer … [Read more...] about How to Test Percentage Impedance of Transformer?
An electrical substation is an installation with electrical equipment capable of interrupting or establishing electrical circuits and changing the voltage, frequency, or other characteristics of the electrical energy flowing in the circuits. The substation provides interconnection of transmission circuits and transformation between the network of different voltages. The … [Read more...] about Electrical Substation: Equipment, Types, Components & Functions
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 can read about all other types of electrical bushings in … [Read more...] about Transformer Bushing Types : RIP Bushing vs OIP Bushing
The combination of more than one conductor per phase in parallel suitably spaced from each other used in an overhead transmission line is defined as a bundled conductor. The individual conductor in a bundle is defined as a sub conductor. Bundled conductors in transmission lines are commonly used to increase electrical capacity and reduce corona and radio noise at voltages … [Read more...] about Bundled Conductors in Transmission Lines
A current transformer (CT) is a type of transformer that is used to measure AC current. It produces an alternating current (AC) in its secondary which is proportional to the AC current in its primary. Current transformers, along with voltage or potential transformers are Instrument transformer. Current transformers are designed to provide a scaled-down replica of the current … [Read more...] about Current Transformer (CT) – Construction and Working Principle
