What is a  Shunt Reactor?


Shunt Reactor Definition


A shunt reactor is defined as an electrical device used in high voltage power systems to stabilize voltage during load changes.

Voltage Stabilization


It controls dynamic overvoltage and provides capacitive reactive power compensation in systems above 400kV.



Impedance Types


Shunt reactors come in gapped core or magnetically shielded air core types to maintain constant impedance and avoid harmonic currents.



Loss Measurement Methods


Losses are measured at lower voltages for high voltage reactors and scaled up; the bridge method is preferred due to the low power factor.


 

Operating Conditions


Must handle continuous voltage without overheating, ensuring it operates within safe temperature limits.

What is Automatic Voltage Regulator?
What is Automatic Voltage Regulator?
An automatic voltage regulator is employed to regulate voltage, converting fluctuating voltages into a constant one. Voltage fluctuations mainly stem from variations in the load on the supply system. Such voltage variations can damage the equipment within the power system. These fluctuations can be mitigated by installing voltage - control equipment at various locations, such as near transformers, generators, and feeders. Multiple voltage regulators are often placed throughout the power system t

What is Static Voltage Regulator?
Types of Static Voltage RegulatorThe static voltage regulator is superior to electromechanical regulators in respect of the accuracy of control, response, reliability and maintenance. The static voltage regulator is mainly classified into two types. They are;Servo Type Voltage RegulatorMagnetic Amplifier RegulatorThe types of static voltage regulator are described below in details;Servo Type Voltage RegulatorThe main feature of the servo type voltage regulator is the use of the amplidyne.

What is Arc Extinction Circuit Breaker?
What is Arc Extinction Circuit Breaker?
When the current-carrying contacts of a circuit breaker separate, an arc forms and persists briefly after contact separation. This arc is hazardous due to the heat energy it generates, which can produce explosive forces.A circuit breaker must extinguish the arc without damaging equipment or endangering personnel. The arc significantly influences the breaker’s performance. Interrupting aDC arcis inherently more challenging than anAC arc. In an AC arc, the current naturally reaches zero duri

Air Break Circuit Breaker
Air Break Circuit Breaker
In an air break circuit breaker, the arc is initiated and extinguished in substantially static air as the arc moves. These breakers are used for low voltages, generally up to 15 kV, with rupturing capacities of 500 MVA. As an arc-quenching medium, air circuit breakers offer several advantages over oil, including:Elimination of risks and maintenance associated with oil use.Absence of mechanical stress caused by gas pressure and oil movement.Elimination of costs from regular oil replacement due to
