LINETRAXX® NGRM500

De NGRM500 is alleen bedoeld voor gebruik in hoogohmig geaarde systemen. In deze systemen bewaakt de NGRM500:

  • de stroom via de aardingsweerstand (NGR);
  • de spanning tussen het sterpunt van de transformator en de aarde (spanningsverlies van de aardingsweerstand (NGR));
  • de toestand van de aardingsweerstand (NGR).

Door de individuele parameterinstelling kunnen de parameters in elk geval aan de systeem- en gebruiksvoorwaarden ter plaatse worden aangepast om zo aan de vereisten van de normen te voldoen.
