What is mean CT Saturation? How to calculate?

Answer Posted / raseelrasheed

SATURATION POINT CAN FIND USING OPEN CIRCUIT CHARACTERISTIC
TEST WITH HELP OF SECONDARY INJECTION KIT,
at first keep the primary and secondary of ct get opened
and connect the kit to secondary of ct,measure and note the
voltage and current and plot the relation graph,
we can see saturation at a point where 10% increase in
voltage causes 50% rise in current.this point is known as
knee point of saturation.

it can also find automatically using modern test kits like
omicron ct analyser etc

hope my answer helpful for u

3 shows a 415 V, 3-phase generator supplying a 3-phase 415/110 V transformer. Draw the individual and combined impedance diagrams to a base of 10 kVA. Determine the system fault kVA and the fault currents at the 415 V and 110 V busbars for short circuit faults on the transformer input or output terminals. Work in p.u. values of impedances.
