Den nye LINETRAXX® PEM353 adresserer applikationer i lavspændingsdistributionen (NSHV), datacenter og bygningsinstallationer. Som et moderne indikatorinstrument for elektriske mængder er det lige så velegnet til overvågning af spændingskvalitet (strømkvalitet) og til energidataovervågning.
Med det standardiserede hus (DIN 96 x 96 mm) er det beregnet til montering på frontpanelet. Den lave profil på 7 mm sikrer næsten problemfri integration.
Som en del af energidataovervågningen giver PEM353 de målte mængder med høj nøjagtighed af aktivt arbejde (klasse 0,5 S). Aktiv, reaktiv og tilsyneladende energi tælles pr. Fase og som totalværdi. Således kan op til tre enkeltfasessourcer registreres. Andre former for energi, sådan. B. Trykluft, vand og gasmålere detekteres ved hjælp af pulsräkneren. Billedet afrundes ved at registrere de daglige energiværdier i de sidste 2 måneder og de månedlige energiværdi de sidste 3 år.
Et andet fokus var på brugervenlighed. Den baggrundsbelyste LCD-skærm er udstyret med en almindelig tekstvisning: Målte variabler er tydeligt læsbare.
Hurtig og intuitiv betjening - dvs. uden en lang træningsperiode - er mulig med de fire knapper og knappen funktionen, der vises direkte ovenfor.
PEM353 måler alle relevante parametre for strømkvalitet som f.eks:
Total harmonisk forvrængning (THD), Total ulige harmonisk distraktion (TOHD), Total jævn harmonisk forvrængning (TEHD), TDD (Total efterspørgselsforvrængning)
Individuelle harmoniske - op til 31. rækkefølge
k-faktor, peak og power factor
Asymmetri
Den fjerde nuværende indgang kan bruges til N-leder måling. En mulig overbelastning af N-lederen med 3n-harmoniske kan således registreres tidligt. Dette reducerer risikoen for brand og, når det drejer sig om enfasede forbrugere, risikoen for overspænding på grund af en N-lederbrud.
På grund af dets omfattende udstyr er PEM353 egnet til overvågning af spændingskvalitet og energidataovervågning og bidrager til sikker systemtilgængelighed ved at overvåge N-lederen.
