ZKSW 60...ZKSW 300, Indoor Interposing Current Transformer Series

More Views

ZKSW 60 ...ZKSW 300, Indoor Interposing Current Transformer Series, Low Voltage 0,72 kV, are winding current transformers with galvanic separated primary and secondary windings. Both windings are mounted on a toroidal core. The active part is completely enclosed by two ultrasonically welded (ZKSW 300: snap-on) half-housings made of an impact-resistant polycarbonate plastic housing. The housing is viscoplastic, flame resistant and self-extinguishing.

Wound current transformers for indoor use, primary current 1 ... 20A, secondary current 1 or 5A with transparent terminal cover. For measuring (and protection) equipment.

Application

1. At lower operating currents, when no direct measurement is desired (electrical isolation of the measuring circuit, keeping the operating voltage away, measuring instruments nominal current not equal to the operating current).
2. for connection to main transformer to the following purposes:
a) To reduce the conduction losses of long measuring lines: Reduce from e.g. 5 to 1 A at the installation location of the main transformer and, if necessary, increase from 1 to 5 A at the measurement location.
b) To protect sensitive equipment against overcurrents by means of a small overcurrent limiting factor with the most accurate selection of the actually required rated burden.
c) For matching the secondary current of the main transformer to the rated current of the equipment to be connected.

 

 

 

 


.    Bei kleineren Betriebsströmen, wenn keine direkte Messung erwünscht ist (galvanische Trennung des Meßkreises, Fernhalten der Betriebsspannung, Meßgeräte Nennstrom ungleich dem Betriebsstrom).
2.    Zum Nachschalten an Hauptwandler zu folgenden
Zwecken:
a) Zur Verringerung der Leitungsverluste bei langen Meßleitungen: Am Einbauort des Hauptwandlers untersetzen von z.B. 5 auf 1 A und bei Bedarf am Ort der Messung wieder heraufsetzen von 1 auf 5A
b) Zum Schutz empfindlicher Geräte gegen Überströme mittels kleinem Überstrom-Begrenzungsfaktor bei möglichst genauer Auswahl der tatsächlich erforderlichen Bemessungsbürde.
c) Zum Anpassen des Sekundärstromes des Hauptwandlers an den Nennstrom der anzuschließenden Geräte.
