Metering Transformers

MSI Metering Transformer
There are two types of metering transformers: potential transformers (for measuring voltage) and current transformers (for measuring current). These are used when the quantity being measured exceeds the capability of the measuring equipment. Magnetic Specialties can design a P.T. or C.T. for a variety of conditions to meet your accuracy needs.


  • C.T. accuracies better than 1%
  • P.T. accuracies better than
  • Up to 60 KV BIL for Potential Transformers
