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 on system voltage, the equipment types and characteristics used in switching stations are … [Read more...] about What is Switching Station? | Working and Layout

Electrical Substation: Equipment, Types, Components & Functions
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. What is the Substation? A substation is an installation that interconnects elements of an electric utility's system. These elements … [Read more...] about Electrical Substation: Equipment, Types, Components & Functions
Bundled Conductors in Transmission Lines
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
Circuit Breaker Definition, Working Principle and Arcing Phenomenon
Circuit Breaker Definition As the name indicates, the circuit breaker means the device which breaks (Open) the circuit under the abnormal condition and protects the system from hazards. The function of a circuit breaker is to isolate the faulty point of the power system in case of abnormal conditions such as faults. Keep reading to understand the working principle of … [Read more...] about Circuit Breaker Definition, Working Principle and Arcing Phenomenon
Classification or Types of Protective Relays
The IEEE defines protective relays as: “relays whose function is to detect defective lines or apparatus or other power system conditions of an abnormal or dangerous nature and to initiate appropriate control circuit action ”. Relays detect and locate faults by measuring electrical quantities in the power system which are different during normal and … [Read more...] about Classification or Types of Protective Relays
