3、 SIPROTEC 7UM62 seriesSiemens relayIntroduction:

The SIPROTEC 7UM62 protective relay can do more than just provide protection. They also provide many additional features. Whether it is a ground fault, short circuit, overload, overvoltage, overclocking or underflocking asynchronous situation, protective relays can ensure the continuous operation of the power station. The SIPROTEC 7UM62 protective relay is a compact device developed and designed specifically for protecting small, medium, and large generators.

Feature:

They integrate all necessary protection functions, particularly suitable for protecting:

Hydraulic and pumped storage generators

Cogeneration plant

Private power plants utilizing renewable energy sources such as wind or biogas

diesel power station

gas power station

Industrial power station

Conventional steam power plant

SIPROTEC 7UM62 includes all necessary protection functions for large synchronous and asynchronous motors as well as transformers.

The integrated programmable logic function (continuous function diagram CFC) provides users with a high degree of flexibility, so they can easily adjust generators, motors, and transformers according to different power plant requirements based on special system conditions. Flexible communication interfaces are open to modern communication architectures and control systems.

The following basic features apply to all versions:

Differential current protection for generators, motors, and transformers

Stator grounding fault protection

Sensitive ground fault protection

Stator overload protection

Overcurrent time protection (timed or inverse timed)

Timed overcurrent protection with directional, undervoltage, and overvoltage protection

Underfrequency and Overfrequency Protection

Overexcitation and Underexcitation Protection

External release coupling

Forward power and reverse power protection

Negative sequence protection

Circuit breaker failure protection

Rotor grounding fault protection (fn, R-measurement)

Motor start time monitoring and motor restart prohibition
