5 SETTINGS 5.4 PROTECTION ELEMENTS
By making the characteristic angle adjustable from 0º to 360º in steps of 0.01º, a variety of operating characteristics can be
achieved as presented in the figures below. For example, for an angle of 0º, the element would operate as a 32 Forward
Power element, while if setting an RCA angle of 180º, the element would operate as a 32 Reverse Power element. For
angles of 90º and 270º, the case would be similar but with reactive power.
Figures (a, b, c, d, e, f) below shows settings for different power applications.
