Current Transformers (CTs)

Current transformers (CTs) are the sensing element behind accurate electric metering, stepping down high primary currents to a safe, measurable signal for power meters and energy monitoring systems. Emergent Metering's CT collection offers a wide range of amperages with standard 0-5A secondary output, plus split-core and solid-core designs for both new installations and live retrofit projects.

Choose split-core current transformers for fast, no-downtime installation around existing conductors, or solid-core CTs for the highest accuracy in new builds. With ratings spanning from small branch circuits up to thousands of amps, these CTs pair with revenue-grade meters, LoRaWAN current sensors, and sub-metering panels to measure load, verify utility bills, and support energy management programs.

Browse the collection to find the right CT ratio and window size for your conductors. Not sure which amperage or core type fits your application? Contact our metering team for help matching CTs to your meter and panel.
