Method for determing dynamic short circuit withstand capability of installations in meshed cable MV-networks, during switching on a fault

Stedin is the Distribution Grid Operator in the western part of the Netherlands and is known to be a “slim network operator” which means that it is only responsible for managing the gas and electricity networks. In this paper a method will be described with which Stedin proved that the dynamic short circuit withstand capability of the installations in the Medium Voltage (MV)-rings can dynamically withstand the immediate occurring fault current after switching on a fault.
