UniGear Digital is a new solution implemented to a traditional UniGear switchgear. It is
accomplished by using well-proven components such as current and voltage sensors, Relion
®
protection relays and IEC 61850 digital communication. Commissioning is very similar to
commissioning activities run on traditional UniGear switchgear. Differences in procedures
are corresponding to implementation of Process bus and GOOSE functionalities and usage of
sensors. The traditional method of commissioning activity starts with primary injections,
then continues with protection relays testing, apparatus functionality verification, etc., and
ends with testing of the communication if applicable. In UniGear Digital, commissioning
must start with verification of IEC 61850 digital communication, particularly with the Ether-
net network check. After commissioning of the Ethernet network, there is no restriction re-
garding the order of other commissioning activities.
