Multi-function machine protection relay Siemens Power Transmission Distribution

The SIPROTEC 4 7UM61 and 7UM62 protection relays can do more than just protect. They also offer numerous additional functions. Be it earth faults, short-circuits, overloads, overvoltage, overfrequency or underfrequency asynchronous conditions, protection relays assure continued operation of power stations. They are compact units which has been specially developed and designed for the protection of small, medium-sized and large generators.

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 combination of functions incorporated in the 7UM62 also offers excellent all-round protection for transformers, large asynchronous motors, synchronous motors.
