The SIPROTEC 7UT differential protection relay are used for fast and selective fault clearing of short-circuits in transformers of all voltage levels and also in rotating electric machines like motors and generators, for short lines and busbars.

The protection relay can be parameterized for use with threephase and single-phase transformers. The specific application can be chosen by parameterization.

In this way an optimal adaption of the relay to the protected object can be achieved. Optionally, a low or high-impedance restricted earth-fault protection, a negative sequence protection and a breaker failure protection can be used. With external temperature monitoring boxes thermo-boxes temperatures can be measured and monitored in the relay.

Therefore, complete thermal monitoring of a transformer is possible, e. The relays provide easy-to-use local control and automation functions. The integrated programmable logic CFC allows the users to implement their own functions, e.

User-defined messages can be generated as well. The flexible communication interfaces are open for modem communication architectures with control system.

The protection relay can be parameterized for use with three-phase and single-phase transformers. In addition to this, a thermal replica is integrated for the supervision of the ohmic losses in the plant. Turn on more accessible mode.
