I think 2:11-2:20 may be wrong? When primary winding has 200 turns and secondary winding has 1 turn, 1000 amps on primary side would produce 1000×200 = 200000 amps on secondary side.

6:18 never leave CT unshorted or unburdened when energized. i had a trouble call from an engineer who burned down a brand new 5k volt breaker because he energized it with the CTs open. what happens is they run away. all the terminal blocks, which are rated to take 30a continuously, all burned into a single smelly glob of plastic

Opening ct circuit on 600 volt rated or less is not as dangerous as the higher voltage rated. The older metering handbook stated this. But once an opinion becomes excepted as fact, reality is lost! We have be changing 3s meters for years without a bypass or shunt. Which opens the current circuit!

CT is a sensor, it's true that it works on electromagnetism principles and to pick up current passing without interrupting it, it has to rely on induction, so it works like a transformer, but it remains a sensor. CT stands for current transducer (= sensor). If we call this device a transformer, then perhaps we can call all radio devices including all mobile phones transformers because they all work on electromagnetism and induction principles, no?
@loftycloud5404

Everyone I know, including myself, and every book and manual I read called it a current transformer. And VT or PT as voltage or potential transformers and both are grouped under instrumental transformers as opposed from a power transformer like a distribution transformer. I get that instrumental transformers are essentially sensors, but everybody and everything calls them transformers because they are in essence that, and are tested and treated as such. Ex: Radio device don't spit out high voltages when back feed, and in fact can't really be backfeed effectively at all, they don't have voltage or turn ratios, are not tied to specific electric grids, no magnetic saturations points, no primary-to-secondary insulations values, etc etc. As far as I found, they are originally called transformers from the beginning.

Depends on the thermal rating factor (TRF) of the CT, and the input ratings of the protection/measuring device. If the TRF=2.0 (very common), the CT will be fine, but will output a continuous 7.5 amps on the secondary. If the protection device can handle that 7.5 amps indefinitely, all will be good. This is routinely done in metering applications in substations.

The magnetic field in the primary will be to low if the primary current is low. The magnetic field must be strong enough to excite the secondary. You can loop the primary back through the ct to increase secondary. If primary only has 1/4 amp, looping through ct 4 times will produce 1 amp on primary, increasing the secondary current, but the ratio will be ÷ by 4.

buy a megger ttr. this will give you a better idea of turns ratio. for example if the transformers primary is 12470v and the secondary is 480/277Y. divide 12470 by 277. this will give you the exact turns ratio results.
