 AC Leakage current transformers
Features
   ●   Center hole-through, easy installation,on
          the safe side.
   ●   Metal casing,better capacity of resisting
         outside surroundings.
   ●   High-sensitivity/accuracy,good linearity.
   ●   
Two series for selection: passive and active
 Applications
   ●   Used in high voltage electric power equipment
         insulation monitoring plant, which is stalled in
         transformers station.Provide exact measure-
         ment for mA leakage current of high voltage
         power equipment, such as transformers
         sleeve, current transformers
