A 400:1 CT is designed to be used with a secondary
burden Rb = 2.5 Ω.
The core is constructed from transformer steel which is normally
operated at a maximum flux density B = 2
Tesla.
The cross-sectional area S of the CT core is
68 cm2. The system X/R ratio is 7.
i) What is the steady state flux the CT can accommodate?
ii) What is the maximum fault
current Ip (expressed as primary side
current) that may be transformed by the CT without a risk of
entering saturation?
