Protecting shunt reactors from various faults and abnormal conditions is crucial to ensure the overall reliability and safety of the grid. The first reason is to limit the overvoltages and the second reason is to limit the transfer of. Presented at the 40th Annual Western Protective Relay Conference Spokane, Washington October 15–17, 2013 Abstract—Shunt reactors are applied to long, high-voltage transmission lines to offset the impact of line charging capacitance to prevent high voltage during lightly loaded conditions. At times, it may be necessary to implement control measures in the cooling circuit based on the condition of the shunt reactor circuit breaker., with one turn or very few turns shorted) and, when undetected and uncleared, may involve more turns or evolve into phase-to-ground faults or even phase-to-phase faults. The grid is changing with investment in long lines to bring remote, renewable resources to load centers. Differential Protection: Compares the.
