Here is the definition of loop feeder. So what does the bold parts mean?
Thanx in advance
Loop Feeder. A loop feeder has its ends connected to a source (usually a single
source), but its main function is to supply two or more load points in between. Each load point
can be supplied from either direction; so it is possible to remove any section of the loop from
service without causing an outage at other load points. The loop can be operated normally closed
or normally open. Most loop systems are, however, operated normally open at some point by
means of a switch. The operation is very similar to that of two radial feeders
