Overview

SMU615 is a dedicated substation merging unit intended for measuring current
and voltage signals from the instrument transformers and merging them into the
standard digital output format that other devices can further use for various power
system protection application purposes. SMU615 itself includes no protection
functionality but it offers the physical interface into the switchgear primary
equipment, that is, circuit breaker, disconnector and earthing switch. SMU615 is
a member of ABB's Relion
simplicity and withdrawable-unit design.
SMU615 has been designed to unleash the full potential of the IEC 61850 standard
for communication and interoperability in the digital substations. SMU615 supports
process bus according to IEC 61850-9-2 LE with IEEE 1588 v2 time synchronization
and both conventional CT/VT inputs and sensor inputs.
