Series reactors — in-line reactance for fault-current limiting; engineered to order, ratings on request

• Connected in series with the circuit to add reactance — the opposite connection to a shunt reactor (which is connected phase-to-earth to absorb reactive power)
• Most common duty is limiting the prospective short-circuit current so downstream switchgear and equipment see a lower fault level
• Part of the same shunt & series reactor portfolio, covering the full spectrum of ratings and voltage levels requested worldwide for every grid configuration
• Engineered to order and tailored to the specific requirements of the power system; ratings are quoted per application
