Busbar system

摘要

A busbar system has a plurality of conductors for mains voltage and a plurality of conductors for a low protective voltage in the busbars. Transformers are provided whose primaries are connected to the conductors for the mains voltage and whose secondaries are connected to the conductors for the low protective voltage. This system allows the low protective voltage conductors to be supplied as often as this is necessary because of the voltage drop, without it being necessary to supply a separate mains voltage cable to each transformer.
