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.

Application of Auto-Reclosing Residual Current Protective Devices in Lightning Protection for Communication Power Supplies
1. Power Interruption Problems Caused by RCD False Tripping During Lightning StrikesA typical communication power supply circuit is shown in Figure 1. A residual current device (RCD) is installed at the power supply input terminal. The RCD primarily provides protection against electrical equipment leakage currents to ensure personal safety, while surge protective devices (SPDs) are installed on power supply branches to protect against lightning intrusions. When lightning strikes occur, the senso

Reclosing Charge Time: Why Does Reclosing Require Charging? What Effects Does Charging Time Have?
1. Function and Significance of Reclosing ChargingReclosing is a protective measure in power systems. After faults such as short circuits or circuit overloads occur, the system isolates the faulty circuit and then restores normal operation through reclosing. The function of reclosing is to ensure continuous operation of the power system, improving its reliability and safety.Before performing reclosing, the circuit breaker must be charged. For high-voltage circuit breakers, the charging time is g
