Product Details
JLSZX8-12W, JLSZX8-17.5W HT METERING UNIT SET
Description
JLSZX8-12W three-phase outdoor cycloaliphatic epoxy resin casting combined transformer (also called HT Metering Unit ), is made up of made up of three single phase semi insulating PTs(Y0-Y0 connection ) and three CTs ( cascade at A, B and C) ; is widely used outdoor for measuring current and electric energy in the electric system with the frequency 50Hz or 60 Hz and highest voltage for equipment 12kV(GB)or 17.5kV(IEC). The product has the feature of high precision, low temperature rise, fireproofing, explosion protection, electricity theft prevention and good dynamic hot stability etc.
