Feature #544
TestBlock condition implemented only in XCBR and not in any of Rxxx and Pxxx logical node
0%
(2019-06): Not accepted. PXXX and RXXX cannot trip directly the breaker. XCBR is needed to trip the breaker.
In order to allow this, binary contacts (input & outputs) should have representation in the standard so that test block condition can be implemented at the binary output level and there is no need to have this attribute in any other logical node.
IEC 61850-7-5
Description
Vendor has implemented TestBlock condition only in XCBR wherein the contact outputs are not operated in test block condition. Test block condition are not implemented in any of Rxxx and Pxxx logical nodes as they are not expected to trip breaker directly.
There exist used cases wherein PTOC/PDIS elements can exist in an IED directly in breaker compartment in field and XCBR node in a bay controller IED located in relay building. In such cases, it is expected that Pxxx or Rxxx nodes are expected to trip directly the breaker.
