What is the diffrence between an ELCB(earth leakage circuit
breaker) and RCCB(residual current circuit breaker)?which
has higher degree of safety and why?
Answer Posted / rvg
ELCB having protection against earth faults, but RCCB having
over current protection as well as earth fault protection.
So RCCB having higher degree of protection.

How does a transformer contribute towards the widespread popularity of ac system over dc?
if there are six generators (3 gas CATT, one Jenbacher o1 MW each, and two nos Diesel 01 no 01 mw other 0.65mw EDGs ( say), 3 CAtt gas set have identical pole pitch,01mw EDG and Jenbacher gas Set have different pole pitch, how their power connection can be done to connect a common bus bar during installation. in short, how different pole pitched generators power connection can be done to connect a common busbar system through generators incomer ACBs.
