In this paper, the new Modified Time Stepping Finite Element Method (MTSF) and Field- Circuit Method (FCM) for the inrusch current calculations of transformers have been presented. The computation time for MTSF and classical Time Stepping Finite Element Method (TSF) in 2D magnetic field analysis have been compared. The MTSF is about two times faster than the TSF method. We analyzed two constructions of the 1- phase transformers. The first one is amorphous modular core transformer (T1) and the second one is the conventional construction with laminated carbon steel core (T2). The comparision of the calculation and measurement results gives a good agreement.
