● Reactive power control, reactive power standard curve cos φ = f(P)
For VDE ARN 4105, the curve cos = f(P) should refer to curve B. The set
default value is shown in curve B.
For e8001, the curve cos = f(P) should be curve A. The set default value is
shown in curve A.
For CEI 0-21, the default value of PFLockInPoint is 1.05. When Vac> 1.05Vn,
Pac> 0.2 Pn, curve cos cp = f(P) corresponds to curve B.
