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.
