Current transformers transient response modelling using electromagnetic transient program (EMTP)

open access: yes, 1997
The subject of this thesis is Current Transformer Transient response study using an electromagnetic Transient program (EMTP). Current transformers are considered eyes for power system protection. Behaviours of protection systems depend largely on information fed to them by instrument transformers.
