i guess im asking the wrong place but does anybody know of a tool to get back into an instagram account?? I somehow forgot my login password. I would love any tips you can offer me!

@Weston Genesis instablaster :)

@Conrad Omar thanks so much for your reply. I got to the site on google and im trying it out now. I see it takes a while so I will get back to you later with my results.

@Conrad Omar it worked and I now got access to my account again. Im so happy! Thank you so much, you saved my ass :D

@Weston Genesis No problem :)

Check out videos on MVCT/ MRCT (used for testing CT).

🙏

MATLAB or EXCEL VBA.

They are all over ebay for cheap. They need a burden resistor to convert the current to voltage.

It will burn

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.

Absolutely

On the 600 volt rated cts the open circuit voltage will only rise a few hundred volts and not thousands., but the higher voltage rated ones will.

He explains this at 10:00 what are the odds I was reading your comment just as I reached this part of the video LOL.

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.

I suppose that would be the direction of the current carrying HOLES as the electrons would be going the other direction NO?

@@johnjacobjinglehimerschmid3555 no. DC current has direction but alternating current doesn't - it alternates. The whole point of RMS is to remove the sign (direction)

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.

If u measure low current using low ratio ct like 5/5, 10/5 ukposts.info/have/v-deo/cKF8aXyxaIFhu30.html

Some of the new cts have higher accuracy at measuring the lower currents in circuits. We use high accuracy, extended range cts on new installations.

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.
