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.
