The voltage transformer is used for measuring current ,electric energy and protective relaying in single-phase or three -phase AC
circuit with the frequency 50Hz or 60Hz and highest voltage for equipment 7.2/12KV
The voltage transformer has the feature of high reliability,low magnetism of core,large creepage distance of external insulation
and maintenance free etc.
key technical data
rated frequency 50/60Hz
load power factor cos φ=0.8 (lagging)
technical standard accords with IEC60044-2 instrument transformers -part 2: inductive voltage transformers
