based on conventional directional ground-fault DEFxPDEF_67/5xN only or alternatively
used together with admittance-based ground-fault protection EFPADM_21YN or
wattmetric-based ground-fault protection WPWDE_32N. A dedicated protection stage
INTRPTEF_67NIEF is used either for transient-based ground-fault protection or for cable
intermittent ground-fault protection in compensated networks. The binary input
X110:BI2 is intended for controlling directional ground-fault protection blocks' relay
characteristic angle (RCA: 0°, -90°) or operation mode (IoSinφ, IoCosφ) change. The
same input is also available for wattmetric protection.
