Comparison of an analytical study and EMTP implementation of complicated three-phase schemes for reactor interruption
Abstract
An analytical study and EMTP (ElectroMagnetic Transient Program) implementation for calculation of overvoltages in three-phase inductive circuits are compared. Capacitive and/or inductive couplings between phases are included in schemes with grounded and nongrounded neutrals. If the time steps for numerical integration are small enough, the EMTP calculation gives reliable and even more detailed and complete results than the analytical approach. Complete listings of input files for the EMTP program are given.
