Bus Fault Protection
Digital feeder and transformer protection logic can
be combined together to provide high-speed bus
fault protection. The 50W2 function will act as a
delayed overcurrent detector (see Figure 4-66). A
fault detected from any feeder relay will activate
a programmable input on the relay. This input will
block the 50W2 function from operating under
normal feeder trip conditions. If a fault occurs on
the bus connected to winding 2 and none of the
feeder relays have tripped, the 50W2 function will
then proceed to trip the breaker after the specified
time delay.
Example
Function 50W2 #1 is programmed with the following
I/O settings: trip Output #2, time delay setting of 7
cycles for proper coordination, and IN4 is set as a
Blocking Input. This application requires no special
logic. In this configuration all feeder relay output
contacts will be in parallel on IN4.
