• Dara current mai shirya a lokacin koyar da capacitor banks.

2. Shunt Reactors

• Neutral Grounded Type (High Voltage Shunt Reactor)
  Wannan nau'in shine da shiga jirgin sama ta da voltage mai yawa ko kuma wurin uku na transformer.

• Tsarin Aiki: Gano reactive power mai kapansu (ko kuma charging power) wadanda ake gina a cikin jirgin sama mai yawa. Yana taimakawa zaɓe overvoltage mai yawa da kuma switching overvoltage.

• Ayyukan Aiki: A yi a cikin jirgin sama mai yawa, ultra-high-voltage, da kuma extra-high-voltage, kamar inter-provincial power lines.

• Neutral Ungrounded Type
  Jinkiri a busbar a cikin masana'antu mai yawan da kuma low voltage levels.

• Tsarin Aiki: Bayar da reactive power compensation, koyar da reactive power daga loads mai kapansu kamar cable lines. Yana taimakawa gyara power factor da kuma dara voltage rise ("voltage floating").

• Ayyukan Aiki: Urban power grids, cable-fed systems, da kuma distribution networks.

3. Filter Reactors

Wadannan reactors suna da shiga jirgin sama ta da capacitors don koyar da LC filter circuit, kamar "cleaner" a cikin masana'antu.

• Tsarin Aiki: Koyar da specific harmonic currents, kamar lower-order harmonics like the 5th, 7th, 11th, and 13th.

•  Ayyukan Aiki:Systems with a lot of harmonic sources, such as large rectifiers, variable frequency drives, and arc furnaces.

Yana taimakawa capacitors zaɓe damage da ita da harmonic overcurrent/overvoltage, kuma yana gyara power quality ta grid.

4. Starting Reactors

Wannan shine nau'in tsohon current-limiting reactor, specifically used to help motors start smoothly.

Tsarin Aiki: Da shiga jirgin sama ta da stator circuit a lokacin mulkin AC motors (kamar induction or synchronous motors). Limits the starting current and reduces the impact on the power grid. Once the motor starts, it's usually shorted out or switched off.

Ayyukan Aiki: Used for high-power motors like large pumps and fans in factories.

5. Arc Suppression Coils (Petersen Coils)

Wannan shine iron-core reactor mai yawa, usually connected to the neutral point of the system - like a "fire extinguisher" for grounding systems. Purpose: In ungrounded or resonant-grounded systems (i.e., systems with neutral grounded through an arc suppression coil), when a single-phase ground fault occurs, it generates an inductive current to cancel out the system's capacitive ground current. This significantly reduces or even automatically extinguishes the fault current at the fault point, preventing intermittent arc grounding and overvoltage. Applications: Distribution networks, small-capacity transformer systems.
Types of arc suppression coils:

• Adjustable Type (manual or automatic adjustment of inductance)

• Fixed Compensation Type (fixed inductance)

• Bias or DC Magnetization Type (adjust inductance by changing the DC magnetizing current)

6. Smoothing Reactors (DC Reactors)

Wadannan reactors suna da shiga jirgin sama ta a cikin HVDC (High Voltage Direct Current) transmission systems, connected in series on the DC side of the converter station or DC line. Purpose:

• Suppress ripple in DC current (smooth out fluctuations);

• Prevent commutation failure on the rectifier side;

• Limit the rate of current rise (di/dt) during DC line faults;

• Maintain continuity of DC current and prevent current interruption.

Ayyukan Aiki: HVDC transmission systems, flexible DC transmission projects.

7. Damping Reactors

Usually connected in series with capacitor circuits, especially in filter capacitor banks. Purpose:

• Limit inrush current and overvoltage when capacitor banks are switched on;

• Suppress oscillations at certain frequencies, such as resonance with system inductance.

Ayyukan Aiki: Frequent capacitor switching scenarios, such as in reactive power compensation devices and filter banks.

In Summary

Akwai nau'ukan reactors da dama, kowane da fannin da take, amma ayyukan da dukkan suke sun hada da: Stabilize current, regulate voltage, filter harmonics, limit surges, and protect equipment. Choosing the right reactor not only improves the stability of the power system but also extends the life of equipment and ensures safe power supply.
