What is mean CT Saturation? How to calculate?
Answer Posted / ayub
CT saturation is a term used to describe the state wherein
a CT is no longer able to reproduce an output current in
propotional to its primary current or as per its Ratio
The basic reason for CT saturation is due to the property
of the core which goes to magnetic sturation due to number
of reasons like large primary current or high burden at
the secondary or an open circuit in the secondary
The saturation can be found out in the following way
Apply voltage to the secondary windings of CT and gradually
increase the voltage noting down the current . initially
you will find that voltage and current are following a
leniear path and as you increase the voltage you will find
a point where 10% increase in voltage results in 50%
increase in current . This point is practically taken as
saturation point
