A change-detection algorithm for short-circuit fault detection in closed-loop AC drives [PDF]
, 2013 This paper deals with an on-line method for turn-to-turn short-circuit fault detection in low-voltage permanent-magnet synchronous machine drives. Due to the closed-loop control, the fault effects are reflected in the voltage.

Известия высших учебных заведений: Проблемы энергетики, 2019 . A method is proposed for calculating the initial value of the periodic term of the short- circuit strength of a dual-circuit overhead transmission line using multiphase replacement circuits. The method takes into account the electromagnetic connections
