SIPROTEC 5 – Earth fault detection
80% of faults are earth faults
Reliable detection – essential in transmission and distribution
• Star point treatment often
compensated
• Different methods with dedicated
devices
Distribution grids 10/20/30/110kV
• Full parallel operation of different
methods
• Increase of reliability
• Saving costs
• Saving engineering efforts

Situation
• Calculation of protection settings & thermal
limits for worst case conditions
• Restrictive limits are to high during >90%
of the year
Solution:
• Automatic adaption of protection settings
• Increased limits during >90% of the year
• Enhanced capacity of the transmission
system without building new lines
How is this done:
• Calculation of settings to be adapted on
control center level
• Download of new settings to SIPROTEC
protection relays using IEC 61850
