What is a Step Up Transformer?
Definition: A step-up transformer transforms the low voltage on the primary side to the high voltage on its secondary side. The current on the secondary
Minimum Oil Circuit Breaker(MOCB)
Definition: A circuit breaker that uses a small amount of oil as an arc quenching medium is called a minimum oil circuit breaker. It is
What is a Circuit Breaker? Definition, Working, Types & Applications
A circuit breaker is a type of switch designed to interrupt the flow of abnormal, or fault current. When a high current flows through a
Hot Wire Ammeter- Construction, Working Principle & Diagram
A hot wire ammeter is an instrument that measures the electric current through a wire by heating and expanding it. These instruments have a slow
Electrical Earthing
Definition: Electrical earthing is the process of directly discharging electrical energy to the earth using low-resistance wire. This is done by connecting the equipment’s non-current-carrying part
Automatic Voltage Regulators (AVR) For Generator
Maintaining a constant voltage at different levels in a power system is crucial. Several techniques are available for voltage control at different levels. An Automatic
Types of Faults in Power System
This article describes the different types of faults in power system, such as LLL, LL, LG, LLG, and LLLG faults. Faults are defects that cause
Symmetrical & Unsymmetrical Faults
Two common types of faults encountered in power systems are symmetrical and unsymmetrical, each with distinct characteristics and implications for system operation and protection. When
Symmetrical Components
The method of symmetrical components simplifies the analysis of unbalanced three-phase power systems under normal and abnormal conditions. This method simplifies the problems of unbalanced
Sequence Impedance
The sequence impedance of a power system is crucial in understanding how the system behaves under asymmetrical fault conditions. The system’s performance can be determined
