Hello Subscriber
today we take a look at the different power supply systems used behind distribution transformers. They are in the IEC-world unified using abbreviations like TN-C or TN-S.
Which system is preferred in your utility?

Usually the power supply systems are named with single phase, three-phase three wire or three-phase four-wire. The German VDE and the IEC60364-1 have unified the supply systems based on grounding.
