RE NA003 - atsinaujinančių energijos šaltinių apsaugos sistema

The new grid and system protection is at home all over the world and guarantees a secure link between decentralized energy producer and public grid. 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 via Open Setup. This allows for permanently programmed, country specific standards to be individually adapter if required. 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
 

The characteristics of NA003 as a good grid and system protector:

  • Functional safety
  • Voltage drop protection; overvoltage protection; monitoring of voltage quality
  • Frequency drop protection; frequency rise protection
  • Detection of off-grid operation
  • Wide rated voltage and rated frequency range, adjustable rated voltage

 

 

Iconography that presents where NA003 have to be installed:

  1. Renewable Energy source (sun, wind)
  2. Conversion renewable Energy into electricity (wind turbine, PV panels)
  3. Power electronic converter
  4. Energy storage
  5. Protecting system (DA003 and switches)
  6. Public grid
