Figuur 5.32: Aardingsweerstand
Opmerkingen:
Als de referentie-impedantie niet ingesteld is, wordt de waarde van ZREF beschouwd
als 0.00 .
ZREF wordt op nul gebracht (0.00 ) als men de CAL-toets indrukt wanneer het toestel
niet verbonden is met een spanningsbron.
ISC wordt berekend zoals beschreven in hoofdstuk 5.6.1.
Als de gemeten spanning de bovenvermelde bereiken overschrijdt, wordt het U
resultaat niet berekend.
Grote schommelingen in de netspanning kunnen de meetresultaten beïnvloeden (het
ruisssymbool verschijnt in het berichtenveld). In zulk geval is het raadzaam enkele
metingen te herhalen om te controleren of de waarden stabiel zijn.
5.7 Aardingsweerstand
De aardingsweerstand is één van de belangrijkste parameters voor beveiliging tegen een
elektrische schok. De aardinsinstellingen, bliksemafleidersystemen, lokale aardingen e.d.
kunnen gecontroleerd worden via een aardingsweerstandtest. De meting is in
overeenstemming met de EN 61557- 5 norm.
Zie hoofdstuk 4.2
Testparameters voor aardingsweerstandmeting
