Split-Core Current Transformers
Small, Medium and Large Sizes
Description
Siemens Split-Core Current Transformers (CTs)
provide linear output voltage that is directly
proportional to the input current. These transformers
are safely and easily installed over existing electrical
power lines without disconnecting the lines or
interrupting service.
Siemens energy monitoring components are used for a
variety of applications including building automation,
tenant submetering, performance verification, energy
management, and new technology assessment. These
devices are targeted for use with the Siemens MD
Series Power Meters.
