Answer 2

The use of reactors permits the ins'tallation of circuit breakers of lower ratings.

• A reactor is a coil with a significant number of turns and a high ohmic resistance value.
• Reactors are used to prevent short circuit currents, which can cause damage to power system equipment. Reactors are the extra reactance put in sequence with the system for protection.
• Reactors are also utilized to safeguard various rated circuit breakers. They are used to restrict short circuit currents based on circuit breaker capacity.
• As a result, while making modifications to the system, we don't have to replace the circuit breakers; instead, we may add reactors while using the same circuit breaker, saving time and money.
