Abstract

Dry-type air core reactor is used widely in power systems and its inter-turn short circuit is the common fault.For reducing the loss due to the short circuit fault and increasing on line detection accuracy of inter-turn short circuit fault of reactor

in this paper

the inter-turn short circuit on line detection method based on the power factor is proposed.The theoretical analysis of the reactor in normal operation and power factor variation of the reactor in the inter-turn short circuit is made on the basis of electromagnetic field theory

the ANSYS Maxwell is used to establish a finite element model to simulate the calculation of power factor variation.Then

the reactor sample with 13 encapsulation and total of 41 layers of coils is tested at different voltages and the feasibility of the detection method is verified by the combination of simulation and test result.
