Reliable Current Measurement for Electrical Metering
Current transformers allow measuring equipment to monitor high electrical currents without routing the full primary current directly through the measuring instrument. The ABB CT1M-10 800 converts an 800 A primary current proportionally to a standard 5 A secondary signal, enabling compatible ammeters, multifunction meters and energy meters to perform indirect current measurement.
The CT1M range is designed for electrical distribution and energy-efficiency applications where accurate and dependable current measurement is required. The CT1M-10 through-primary format provides installation flexibility for cables and busbars, while its defined accuracy classes and VA ratings allow the transformer to be matched to the requirements of the connected metering circuit.
Typical Applications
- Electrical energy metering systems.
- Main and sub-distribution switchboards.
- Industrial electrical distribution panels.
- Indirect current measurement with ammeters.
- Multifunction electrical measuring instruments.
- Energy monitoring and management systems.
- Commercial and industrial power-distribution installations.
