Dry-type air-core reactor

as important equipment in power system

is used mainly to limit the short circuit current and provide reactive power compensation.Therefore

stable operation of reactor is critical the whole safety and stability of the grid.It is cold in the north part of China in winter

with frequent burning of reactor and especially in the closed operation of the reactor.Therefore

in this paper

both insulation and mechanical performance of the winding under different low temperatures is studied so to find the influence of low temperature on the performance of the reactor winding
