Vi er stolte af at kunne annoncere udgivelsen af vores seneste og mest avancerede overvågnings- og beskyttelsesudstyr type NGRM 700 (neutral grounding resistor NGR -Monitor).
Dette beskyttelsesudstyr er branchens førende relæbeskyttelse, og giver ekstra sikkerhed i forbindelse med transformatorer og generatorer modstands nulpunktsjording. Det ikke blot opfylder de lovgivningsmæssige krav på området, men overstiger begrænsningerne i det gængse udstyr der forfindes på markedet, til dette formål.
Dette er både at detektere såvel åbne som kortsluttede modstande i nettet, med både aktiv og passiv overvågning.
NGRM700 kan registrere jordfejl ved at overvåge AC og DC strømme i nulpunktsjordings modstanden, gennem selektiv filtrering. Endvidere kan det samtidig afsløre, en fejl fra nul til jord.
Udstyret er også i stand til måle fasespændinger og kan derfor angive, hvilken fase der er fejlbehæftet og har en jordfejl. Dette kombineret med en impulsgenerator, bidrager og hjælper til at fremskynde en hurtig fejlfinding, og derved undgå dyre driftafbrydelser og nedetider.
Den aftagelige grafiske skærm kan monteres i tavle eller være fastgjort til relæet. Hver enhed er udstyret med Ethernetkommunikation til brug af fjernovervågning. Udstyret er nu tilgængelige for installation.
