SIPROTEC 7VE85

The SIPROTEC 7VE85 paralleling device is specifically designed for the synchronization of generators (power-plant units) with the power grid or synchronization of 2 electricity-supply systems. Its main function is the 1.5-channel and 2-channel paralleling function.

A variety of monitoring functions are utilized by the software as a means of achieving high levels of security and reliability. Duplication is also done for the most important hardware components. Two measuring algorithms are used in accordance with the multi-channel redundancy, which helps avoid overfunctions through systematic errors.

The SIPROTEC 7VE85 can be used in a wide variety of applications as its reliability and flexibility allows it to adapt to equipment requirements.
