Test switch
The test system COMBITEST intended for use with the IED
670 products is described in 1MRK 512 001-BEN and 1MRK
001024-CA. Please refer to the website:
www.abb.com/substationautomation for detailed information.
Due to the high flexibility of our product and the wide variety
of applications possible the test switches needs to be
selected for each specific application.
Select your suitable test switch base on the available
contacts arrangements shown in the reference
documentation.
However our proposals for suitable variants are;
Single breaker/Single or Three Phase trip with internal neutral
on current circuits (ordering number RK926 315-AK).
Single breaker/Single or Three Phase trip with external neutral
on current circuits (ordering number RK926 315-AC).
Multi-breaker/Single or Three Phase trip with internal neutral
on current circuits (ordering number RK926 315-BE).
Multi-breaker/Single or Three Phase trip with external neutral
on current circuit (ordering number RK926 315-BV).
The normally open "In test mode" contact 29-30 on the RTXP
test switches should be connected to the input of the test
function block to allow activation of functions individually
during testing.
Test switches type RTXP 24 is ordered separately. Please
refer to Section
"Related documents" for reference to
corresponding documents.
RHGS 6 Case or RHGS 12 Case with mounted RTXP 24 and
the on/off switch for dc-supply are ordered separately. Please
refer to Section "Related documents" for reference to
corresponding documents.
