For VDE ARN 4105, the curve cos Ø = f(P) should refer to curve A. The set
default value is shown in curve A.
»
For TOR, the curve cos Ø = f(P) should be curve B. The set default value is
shown in curve B.
»
For CEI 0-21, the default value of PFLockInPoint is 1.05. When Vac> 1.05 Vn,
Pac> 0.2 Pn, curve cos Ø = f(P) corresponds to curve C.
