9.3 HSBO- trip from the distance protection zone 1 function (ZM1)
In order to test the performance of the high-speed binary out function alone without any
interference from other functions the binary outputs configured for the HSBO function
must not carry any other signals. For example, if the outputs are shared with the TRIP
function the TRIP function should be switched off.
Switch the HS function off as well.
Whenever a trip appears during these tests, it should be possible to block it through the
function input HSBO-BLKHSTR.
Note that no carrier send will be issued from the distance protection function zone 1.
Activation of HSBO-BLKZCTR or HSBO-BLKHSCS should not block any outputs in
this test.
Use the 3-phase test set to achieve the specified conditions.
Suggested fault characteristics, for all types of faults:
• Prefault conditions: U
phase
= 63.5 V, 0° I = 0.0 A, 0ë
• Fault conditions: Within set operating characteristic of ZM1 function.
