Operation on a TN system
Overview
The converter is suitable for connection to a TN system.
Requirement
The following applies to the connection of converters to a TN system:
• Converter with integrated or external line filter:
– Operation on TN systems with grounded neutral point is permissible
– Operation on TN systems with grounded line conductor not permissible
• Converter without line filter:
– Operation on all TN systems permissible
Description
The TN system transfers the PE protective conductor to the installed electrical installation using
a conductor.
Generally, the neutral point is grounded in a TN system. There are versions of a TN system
with grounded line conductor, e.g. with grounded L1.
The TN system can transfer the neutral conductor N and the PE protective conductor either
separately or combined.
