Dry-type Iron Core Series Reactor
03-18 2025 | By:
Dry-type reactors are an important part of the power supply system. The most common ones are series reactors and shunt reactors. Series reactors, also known as current limiting reactors, are placed between the load and the power supply to limit short-circuit current.
There are also dry-type reactors connected in series or in parallel with capacitors in power filters to limit high-order harmonic currents. In a typical 35kV or 10kV power grid, reactors are a good way to compensate for reactive power. By increasing or decreasing the number of shunt reactors in the power supply line, users can change the line voltage.

The role of dry-type reactors
1. Compensate for the capacitive current when the power supply is lightly loaded, thereby improving the system power factor and reducing transient overvoltage.
2. Improve voltage distribution on long-distance transmission lines
3. Reduce line losses and improve power factor
4. When shunt reactors are connected in parallel with large equipment, they can reduce steady-state voltage transients on high-voltage transmission lines, making it easier to run multiple generators in parallel at the same time
5. Alleviate resonance problems caused by long cables connected to the generator
6. When the neutral point of the reactor is grounded, it can be used to compensate for line capacitance between three phases or between phases and neutral points. Shunt reactors can also eliminate secondary arc currents.
