transformer 3 ph, 225 kva pri 480v, sec 208v. primary
neutral connected to system, is secondary neutral to be
grounded and how
differentiate between remote backup relay and local backup relay?
In our domestic single phase line if you don't have a ground connection (earthing)how will you separately use earth in a specific power supply board.
how to measure the transformer resistance values(dyn11)?and howmuch the minimum value?
can transformer work on dc or not?if we increase the inductance of transformer can it happen to work on dc?
wat is syncronization . wat parameter will take for syncronization.
Role of active and reactive Power sharing in between two synchronized Generators, Droop Setting role ?
What is the difference between vector surge relay (78) and Pole slip relay (98G)
25 kva load,
in indoor type circuit breakers why only the corner breaker trips specially during cold season. What is the reason.
What is the effect of positive feedback on stability of the system?
