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
