There are 2 different behavior modes of PVARP based on
programmed mode, which is described below.
•
In P-synchronous modes (e.g. DDD), the PVARP timer
is started after : Vp, Vp(WKB), Vp(SW), Vp(BU)
•
In R-synchronous modes (e.g. DDI), the PVARP timer is
started after: Vp, Vp(SW), Vp(BU), VES, Vs and
Vs(AVC).
•
After a VES, the parameter PVARP after PVC is
automatically extended to PVARP + 150ms, up to a
maximum of the user programmable “PMT VA Criterion
limit” + 50 ms. This parameter was formerly known as
PMT protection after PVC.
This behavior is demonstrated in
Figure 11
