Fig. 15

An REF 54_ feeder terminal used for the protection, control, measurement and supervision func-
tions of a utility feeder (main single-line diagram presentation). The neutral point of the supplying 
network is earthed via a low resistance. The scheme is also fully applicable to other types of low-
impedance earthed networks, where the neutral point is earthed effectively or via a low reactance.
