One for all

With its new, optimized grid and system protection, Tele tackles an important problem: many countries - many standards. Effective immediately, the new RE NA003 with its compact design covers all main country standards in one device. All relevant parameters can be flexibly set directly in the field. In addition to the already predefined standards, there is an additional “Open Setup” where the user can create his own configuration without any limitations. This allows for permanently programmed, country-specific standards to be individually adapted, if required. Completely new setups for new grid and system standards can also be easily programmed. For the first time, operation in single and three-phase grids is possible through simple switching. The new grid and system protection from Tele is suitable for medium and low voltages.

Grid and system protection is switched between a decentralized energy producer, such as a photovoltaic system, for example, and the grid of the public energy supply company (EVU) and continuously checks the grid quality. If the voltage or frequency in the public grid rises or falls beyond permissible limits, the small power station is immediately decoupled. In this way, unintentional, isolated operation that is dangerous for maintenance personnel is prevented.

The corresponding parameters for this separation process are standardized differently in different countries. Now, for the first time Tele has brought grid and system protection to the market that can be freely configured in the field and thus can be individually adapted to your requirements. To prevent misuse, password protection or a sealing of the device is possible at the official delivery point.
