Combined CT & PT Units

Combined CTPT units, also known as metering units, revolutionize the field of electrical power monitoring and control by integrating current transformers (CTs) and voltage transformers (VTs) into a single, compact solution. These units accurately measure current flow and voltage levels, providing a comprehensive picture of the electrical system being monitored. With improved accuracy and efficiency, combined CTPT units, or metering units, play a vital role in power monitoring, load management, fault detection, and maintenance across various medium voltage applications.
