The fault analysis of transformer to develope protective relaying algorithm for transformer

변압기보호계전 알고리즘 개발을 위한 변압기의 고장해석

This paper deals with a simulation method of faults in a power transformer. Using the [R],[L] matrix supplied by the auxiliary routine of EMTP called BCTRAN, the turn to ground fault and turn to turn fault are simulated and the inrush condition is simulated using saturable transformer model. Data from simulations can be used to identify the response of the digital protection algorithms for transformer.
