Me kuke so kuɗi a cikin series air-core current limiting reactors?

Principle of Current Limiting Based on Inductance:

• According to Faraday's law of electromagnetic induction, when current flows through the windings of a reactor, it generates a magnetic field around the windings. This magnetic field, in turn, opposes the change in current, as described by Lenz's Law.

• A series-connected air-core current-limiting reactor utilizes this principle. When a short-circuit fault or an excessive current occurs in the circuit, the inductance of the reactor impedes the rapid rise of the current, limiting its magnitude. This protects other equipment in the circuit from the impact of high currents.

• For example, in a power transmission system, if a short circuit occurs on a line, the series-connected air-core current-limiting reactor will quickly increase the impedance of the circuit, preventing the short-circuit current from reaching excessively high values instantaneously. This provides additional time for protective devices, such as circuit breakers, to operate, ensuring the safety and stability of the system.
