Answer Posted / vamsi krishna

EVERY SYSTEM HAS ITS RESPONSE AS 1) TRANSIENT RESPONSE AND
2) STEADY STATE RESPONSE

TRANSIENT STATE IN A SYSTEM IS THAT WHICH OCCURS FOR A
MILLI SECONDS DURATION OF TIME. IT IS ACTUALLY OCCURENED
DUE TO DIFFERENT CAUSES AS

1) SUDDEN ENERGISING OF THE SYSTEM.

2) LOADING THE SYSTEM SUDDENLY.

3) WHEN SYSTEM IS TERMINATED WITH THE NON CHARACTERISTIC
IMPEADENCE....ETC

THE MAIN REASON FOR THE TRANSIENTS IS THE PRESENCE AND
EFFECT OF ENERGY STORAGE ELECMENTS IN THE SYSTEM.

THERE ARE A NUMEROUS WAYS OF SOLVING METHODS FOR TRANSIENT
