Optionally, a low or high-impedance restricted earth-fault protection, a negative sequence protection and a breaker failure protection can be used.
In addition to this, a thermal replica is integrated for the supervision of the ohmic losses in the plant. The flexible communication interfaces are open for modem communication architectures with control system. Capacitor Bank Protection go. Line Differential Protection go.
Description Functions Downloads Configurator. Protection for Rail Electrification go. User-defined messages can be generated as well. The SIPROTEC 7UT differential protection relay are used for fast and selective fault telay of short-circuits in transformers of all voltage levels and also in rotating electric machines like motors and generators, for short lines and busbars.
With external temperature monitoring boxes thermo-boxes temperatures can be measured and monitored in the relay. Motor and Generator Protection go. The relays provide easy-to-use local control and automation functions. Turn off more accessible mode. The protection relay can be parameterized for use with threephase and single-phase transformers.
