CBCT used to protect the motor winding from unbalance load it is install on the cable ,in normal balance conditions the sum of the three phase current is zero so secondary current of the ct also zero .when ever unbalance occurs then this unbalance current will flows through the ct then relay sense and trip motor

How do you measure current flow through a 3 core cable using a ct?
To measure current flow through a 3-core cable using a current transformer (CT), you would typically clamp the CT around one of the conductors within the cable. Ensure the CT is properly rated for the expected current and that it is installed in the correct orientation. The CT will produce a proportional secondary current that can be measured with a connected ammeter or monitoring device. Ensure to account for the transformation ratio of the CT for accurate readings.
Core balance current transformer?
whats a core balance current transformer? Core Balance CTs are special CTs used to detect Earth faults & usually used for Restricted Earth Fault Protection. It is a ring type CT through which the cables carrying current of all the three phases (R,Y & B) are passed through. (In a 3phase 3 wire system) Under normal operating conditions, summation of current through the three phases shall be equal to zero. In event of a fault, the summation of the current shall no longer remain zero (zero sequence current shall flow during earth fault) & thus the fault can be detected.
How much will you get for 9 ct gold with metal core?
The value of 9 ct gold with a metal core depends on the current market price of gold and the weight of the item. Generally, 9 ct gold contains about 37.5% pure gold, so you would calculate its value based on that percentage. Additionally, the presence of a metal core may reduce its overall value compared to solid gold items. It's best to consult a jeweler or use a gold calculator for an accurate estimate.

What is ct?
You mean CT. CT means Connecticut the abbreviation for Connecticut is CT get it?
What medical treatment is suggested for balance?
Find out if you have an inner ear problem ie see a doctor. Get a MRI or CT to find out if you have had a stroke in your cerebellum. Don't ride a bike.
Why you use current transformer and rogowski coil both?
if you want to measure a wide range of current, example 1mA to 200A (if the device is intended for the metering and protection), normally CT and rocoil is used together, it is difficult to make rocoil sensitive in range of 1mA, but you can do the task with the CT, but the same CT gets saturated above 5A, in that case rocoil start measuring, since rocoil is air core it wont saturate.
Can you change a ct ratio from 18000 to 5 to a new ratio say 6000 to 5 by removing wire from the core the ct has two coils each with 1800 turns on each one i want to remove 1200 wraps on each?
Most CTs are encapsulated so it is not really practical to unwind the primary winding.
Are tigers illegal pets in CT?
Half of CT,no. Half of CT, yes

What is multiple class CT?
a ct is a current transformer the primary is one turn this can be a hole you pass a wire thru the laminations the wire you pass thru the hole can be 300v 600volt or 13200Volt insulation the core is bolted to the enclosure clamp on ammeter Amprobe are portable multi class current transformers with meters right on the side
