WebMar 3, 2024 · In shorter terms, CT meters are used to measure current, while PT meters are used to measure voltage. Additional Features of CT Metering Sockets CT metering sockets can come with an array of added features that serve their own purposes. For example, one of the most popular electric meter socket types is a meter socket with a disconnect. WebCurrent Transformers. Continental Control Systems does not sell CTs rated for use over 600 Vac, so CTs rated for medium-voltage services must be used. Most medium-voltage CTs output 5 amps at their full scale rated current. For example, the secondary winding of a 500:5 ratio CT will output 5 amps when 500 amps flow through the CT’s window ... ts type null
