The SIPROTEC 7UM6 protection relays have been specially developed and designed for the protection of generators of all sizes and synchronous and asynchronous motors. With the high-performance DIGSI 4 engineering tool, the SIPROTEC 4 devices offer user friendly system solutions for protection, automation and monitoring with high field experience and security.
Features
They integrate all the necessary protection functions and are particularly suited for the protection of:
•Hydro and pumped-storage generators
•Co-generation stations
•Private power stations using regenerative energy sources such as wind or biogases
•Diesel generator stations
•Gas-turbine power stations
•Industrial power stations
•Conventional steam power stations
The device can also be used for protecting synchronous and asynchronous motors.
The integrated programmable logic functions (continuous function chart CFC) offer the user high flexibility so that adjustments can easily be made to the varying power station requirements, on the basis of special system conditions.
The flexible communication interfaces are open for modern communication architectures with the control system.
