Hi Satya, thanks for your kind words...steve

The 5 A secondary rating of the CT always raises questions with students when they see 65A of current flowing during a fault! Intuitively they don't expect to see any current greater than 5 A.!

[@Electricalsteve]

Hi Jason,
Agreed!! I have seen CT wiring connected to telecoms terminals through tiny wiring as the installer doesn’t appreciate that the primary system fault current of 1000’s of amps gets fed through to the CT secondary wiring….

So nicely explained Sir. Is there also a video on case where a Feeder CT saturates during external fault and explanation on the stabilizing resistor and MOVs?

[@alliservices8885]

Thank you Mr. Brooks.

[@Electricalsteve]

You are very welcome

[@anithaid894]

Thanks, upload more. Its very useful.

This high impedance relay same time voltage also developed please mention developing voltage

[@Bitcoinminds]

Hi anitha what degree u r doing

[@ХурбаярХураа]

During the Short circuit moment why do the feeder B C D's currents are not becoming zero?

[@Electricalsteve]

Hi,
Because the generators are feeding energy ( current ) into the fault, this will continue until the protection operates ( which it should ) or the generator voltages collapse. steve

[@bharathi6898]

Nice job sir... I hav one doubt
while any fault occurs in busbars how could you say current flows only in B feeder is null.... there Busbar is common for all the feeder isn't?

[@rahulwable9231]

Nice video, you have explain current on incoming side of main bus bar, please explain on outgoing side of current rating, and bus bar sizing

[@vipulwadkar8502]

Informative 👍

[@Electricalsteve]

Thanks 🙂

[@alfabiro7226]

Thank you for this useful video!

[@shazebhashimkhan3009]

Why Feeder B breaker is OPEN when fault occurred at BUS

[@Electricalsteve]

Hi Shazeb, for the example shown the fault was on feeder B, outside the busbar protection zone. The protection correctly identifies this and only opens the feeder B circuit breaker, disconnecting the fault from the system
