Series reactors are used in transmission lines to limit the flow of current and improve system stability.

• Series reactors are used to limit the flow of current in a transmission line.

• They improve system stability by reducing voltage fluctuations and power surges.

• They can also be used to compensate for line capacitance and improve power factor.

• Examples of series reactors include air-core reactors, iron-core reactors, and...read more

Yes, core loss depends upon frequency.

• Core loss is the energy lost in the magnetic core of a transformer or inductor.

• It is caused by hysteresis and eddy current losses.

• Hysteresis loss is proportional to the frequency and magnetic flux density.

• Eddy current loss is proportional to the square of the frequency and the thickness of the core.

• Higher frequency leads to higher core loss, which can cause overheating and reduced
