Interpose / Matching Current and Voltage Transformers (ICT, IVT)
The transformers can also be used as interposing CT’s for the galvanic separation of two measuring circuits.
The following information is required when ordering (ICT, IVT) according to IEC60044-1, 2:
a- Transformer ratio (5/1, 1/5, 1/1, 3/4, …),(400/100 , 220/110,…)
b- The VA burden
c- Class(measuring) (1, 1+3P , 0.5 , 0.5 + 3P, class of accuracy and accuracy limit factor(ALF) (5P10, 10P10 , …)
