Reactor individual branch loss mutation is one of the important reasons leading to local temperature too high. In order to explore process deviation for dry type hollow shunt reactor loss amplification effect, this paper is establish a loss calculation model of dry-type air-core reactor as the tool, Comparative analysis relationship between the four common types of process deviation and the local branch loss. Calculation results show that the number of turns deviation are the main factor influencing the reactor partial loss, So the reactor production winding process should strengthen the control of the number of turns deviation.
