Example 1: Extending input/output capabilities of a C60 relay
Consider an application that requires additional quantities of digital inputs or output contacts or lines of programmable logic
that exceed the capabilities of a single UR-series chassis. The problem is solved by adding an extra UR-series IED, such
as the C30, to satisfy the additional inputs/outputs and programmable logic requirements. The two IEDs are connected via
single-channel digital communication cards as shown below.
Figure 5–94: INPUT AND OUTPUT EXTENSION VIA DIRECT INPUTS AND OUTPUTS
Assume contact input 1 from UR IED 2 is to be used by UR IED 1. The following settings should be applied (Direct Input 5
and bit number 12 are used, as an example):
The
Cont Ip 1 On
operand of UR IED 2 is now available in UR IED 1 as
DIRECT INPUT 5 ON
.
Example 2: Interlocking busbar protection
A simple interlocking busbar protection scheme can be accomplished by sending a blocking signal from downstream
devices, say 2, 3 and 4, to the upstream device that monitors a single incomer of the busbar, as shown in the figure below.
Figure 5–95: SAMPLE INTERLOCKING BUSBAR PROTECTION SCHEME
Assume that Phase Instantaneous Overcurrent 1 is used by Devices 2, 3, and 4 to block Device 1. If not blocked, Device 1
would trip the bus upon detecting a fault and applying a short coordination time delay.
The following settings should be applied (assume Bit 3 is used by all 3 devices to sent the blocking signal and Direct Inputs
7, 8, and 9 are used by the receiving device to monitor the three blocking signals):
