NA PROTECTION – THE RIGHT SOLUTION FOR EVERY SYSTEM
Depending on the national directive, generating plants (PG) must be switched off in the event of impermissible voltage or frequency deviations in the low-voltage grid. If the permissible limit values in the application rule are exceeded, the grid and system protection with single-fault protection ensures that the generating system is automatically disconnected from the grid. Once the grid voltage or grid frequency is back within the permissible range, the system is automatically switched back on. Furthermore, feed-back to a de-energized grid should be prevented (minimum voltage interlock).
We offer both standard products and customized external NA protection solutions that are adapted to the needs of the respective photovoltaic system.
