Automatic transfer switching equipment

UTXvSZR is a comprehensive solution for HV and MV feeding Power Transformer/Bay switching. It provides fast and reliable Automatic Transfer Switching (ATS) due to either the power lack or feeding Bay Circuit Breaker tripping.

The most important additional functionality of 3rd series compared to the 2nd series is the implementation of the IEC 61850 protocol. In addition UTX 3rd series has a revised front-panel (display, keyboard) and is equipped with the relay PAX package (package of 4 powerful and quick exits) as a standard. Reliable operation of the device is based on precise and quick analog value measurements and precise voltage vectors finding. The devices are equipped with A/C transducers. As a standard, they are equipped with network transmission interfaces Ethernet and TCP/IP and optionally fibre optic communication interfaces for TRbus, AAbus and IEC 870-5-103 protocols.

Optionally, the serial transmission interface of CCBus engineering channel may be lead out to the device front panel. The devices can be equipped with CANBus interface (2 channels) for a superior system. Moreover, UTX line series 2 cooperate with Xserver concentrator, which may be implemented with DNP3.0 protocol.

Applied at MV substation, UTXvSZR is able to operate and monitor 3 or up to 5 CBs.
Installed at HV substation, the device is able to operate and monitor 3 CBs (two CBs of the lines and one of the line coupler). Except the standard ATS modes, UTXvSZR can provide any user with a defined switching scheme, comprising up to 8 voltage groups and 15 CBs.
