Current protection
6.15 Directional over-/under-power protection GOPPDOP/
GUPPDUP (32/37)
6.15.1 Functionality
The directional over-/under-power protection GOPPDOP (32)/GUPPDUP (37) can be used wherever
a high/low active, reactive or apparent power protection or alarming is required. The functions
can alternatively be used to check the direction of active or reactive power flow in the power
system. There are a number of applications where such functionality is needed. Some of them are:
• detection of reversed active power flow
• detection of high reactive power flow
Each function has two steps with definite time delay. Reset times for both steps can be set as well.
