The SIPROTEC 5  7VE85 recognizes the operating conditions automatically and reacts in accordance with the settings.

In “Switching synchronous electrical power systems” operating mode the frequency difference is measured with a high level of accuracy. If the frequency difference is almost zero for a long time, this is referred to as a synchronous electrical power system, for which a wider switching angle can be permitted.

The 1.5-channel parallel switching function  is provided for use in small to medium-sized generators and in electrical power systems.

In this example two distinctly independent methods of measurement decide on the switching conditions.
Furthermore, SIPROTEC 7VE85 offers additional current, frequency, power and voltage protection functions and many
other control and monitoring functions. As a result, the paralleling device offers synchronization and protection functions in a single device. With its modular structure, flexibility and the powerful DIGSI 5 engineering tool, the SIPROTEC 7VE85 device offers Future Proof system solutions with high investment security and low operating costs.

The following modes of operation are covered:

• Switching synchronous/asynchronous electrical power systems
• Switching to de-energized line or dead busbar
• Synchro-check function
• Adjusting commands for voltage and frequency (speed)
