Split Core Standard CT
Current Transformers
DESCRIPTION
Split Core Standard CTs provide linear output voltage
that is directly proportional to the input current. These
current transformers are safely and easily installed over
existing electrical power lines without disconnecting
the lines or interrupting service.
Setra’s energy monitoring components are used for a
variety of applications including building automation,
tenant submetering, performance verication, energy
management, and new technology assessment.
