Reliable Current Measurement for Electrical Systems
Current transformers reduce high primary currents to a standard secondary current that can be safely measured by compatible electrical instruments. The Lovato DM4T1500 transforms a primary current of up to 1500 A into a proportional 5 A signal, allowing connected equipment to monitor electrical loads without carrying the full line current.
Its solid-core design is particularly suitable for new switchboard and control-panel installations where the conductor can be passed through the transformer during assembly. The combination of a large aperture, multiple busbar compatibility and selectable accuracy performance makes the DM4T1500 a practical solution for industrial energy management and electrical distribution applications.
Typical Applications
- Low-voltage electrical distribution panels.
- Industrial switchboards and control cabinets.
- Energy metering and power monitoring systems.
- Digital multimeters and network analysers.
- Ammeters and current indication equipment.
- Protection relays and electrical monitoring devices.
- Manufacturing facilities and process plants.
- Commercial building power-distribution systems.
