Thanks ScottyUK for the SEG stuff. However, as far as I understand the subject and the prevailing detection techniquies, all of the Passive or Active schemes have Non Detection Zone. I have come across a scheme (also referred by alehman), in which the reactive power change is sensed at AVR to...
I understand that if the re-closer operating time is in seconds, then, it shall be enough time to be sensed by protection but if the re-closer operating time is around 0.5 to 0.8 sec, is there any protection to sense and operate with in this duration. I hope one can read between the lines that I...
Thanks Davidbeach & dpc.
However my concerns is for smaller generators to the tune of < 500 kW. Is there any protection available which operates fast enough to ensure that the generator is out of the circuit before the re-closer operates.
Next, what is the minimum operating time of 80-R relay...
I shall appreciate if someone can highlight the conditions which govern, the requirement of transfer trip in interconnection of embedded generators in transmission or distribution utility network.
