The busbar differential protection function (87BB) is the main protection function to protect busbars, and It relies on Kirchhoff’s current law. This law states that the vectorial sum of all currents flowing into a closed area must be zero.

Topics related to busbar protection and how to configure and set the busbar protection parameters have been recorded.

The various types of busbar arrangements are used in the power system. The selection of bus bars is depended on different factors for instance reliability, flexibility, cost, etc.

Single Bus-Bar Arrangement
single bus station with transfer bus (Main and Transfer Bus Arrangement)
double bus-single breaker station
double bus-single breaker station with the transfer bus
double bus-single breaker station with two bus-section and two bus-coupler breakers
one-and-a-half breaker station
double bus-double breaker station
mesh or ring bus station

The parameter set cannot be transferred to the device.

The reason for this is that the parameter for the EN100 module has not yet been updated after changing the IEC61850 system interface. To do so, open the “update” property page of the IEC61850 station and update all parameter sets. A transfer to the device now works again.

Terms of I> mean Time delay O/C, and I>> is instantaneous O/C

problem: 1ph fault but relay give 3ph command in Siemens 7SA522

Solution: In the matrix, u can raise the signal 1ph trip permitted by AR via one BI. Normally Simense relay giving always 3ph trip
