"cos φ - Power
Factor"
0 ‑ 1 Set value of Cos φ.
"Direction / Ex-

The current direction corres-
ponds to the generator
counter arrow system.
Under-Excited Under-excited operation = in-
ductive operation = reactive
power is drawn = reactive cur-
rent is fed in ahead of the
active current.
Over-Excited Over-excited operation = ca-
pacitive operation = reactive
power is supplied = reactive
current is fed in lagging the
active current.
