what will happen if the secondary of current transformer
kept open....

Answer Posted / raxit

because of primary,there is flux linkage in secondary.so
current will flow through secondary.but if there is no close
path,current will not flow.but due to electromagnetic
induction high voltage will be built up across the secondary
terminal and the current transformer will BLAST

Hello everyone, somebody knows what is a "surplice power" ? The hole phrase is: "This rating is appropriate for a generator set paralleled with an infinite bus e.g. a national electrical supply network or grid where the generator set is run at 100% load, 24 hours a day, 365 days a year and any surplice power is exported into the grid" Thanks in advance.
