6.5.2 Functions
General functionality
The 3UG4614 line monitoring relays monitor a three-phase system for phase
asymmetry, undervoltage, phase failure, and phase sequence.
The devices feature a wide-range voltage input and are self-powered (measuring voltage
= rated control supply voltage). The 3UG4614 line monitoring relays monitor all phases of three-
phase AC networks from 160 to 690 V through terminals L1 / L2 / L3 and also draw power from
all three phases simultaneously.
