Can 2 power feeds enter simultaneously through the same busbar?
Thread Content
There are two incoming lines from upstream stations on the same bus in the substation (for example, Bus No. 4). Is it possible to supply power to Bus No. 4 simultaneously?
The phase sequence of the two power cables is the same, which is completely fine; phase alignment needs to be checked before powering them on
Is the term for professional use simply \"single-power supply wiring\"?
It should work with the same power supply; otherwise, a circulating current should occur:D
If power is supplied simultaneously, it is equivalent to two transformers at the upstream station operating in parallel; this is possible provided that the two transformers meet the conditions for parallel operation, theoretically speaking. But it should not be allowed procedurally
It is acceptable if it can be considered as a dual-cable inlet. The text does not state that 4# is a sectional busbar nor that there is a bus coupler; since there are two incoming lines, it is entirely possible to perform phase comparison if the sources are on the same busbar. However, different sources are generally not allowed; a self-provided transmitter can be installed
