Reliable High-Current Measurement for Electrical Systems
Current transformers allow high electrical currents to be measured safely by reducing the primary current to a standard secondary value. The Lovato DM4T3500 converts a primary current of up to 3500 A into a proportional 5 A signal, allowing compatible measuring instruments to monitor the circuit without carrying the full load current.
Its large conductor aperture, high rated burden and solid-core design make it suitable for high-current power distribution systems. When connected to compatible instrumentation, the DM4T3500 can support energy management, load monitoring, electrical protection and preventative maintenance across industrial, commercial and infrastructure installations.
Typical Applications
- High-current industrial switchboards.
- Low-voltage electrical distribution panels.
- Energy metering and power management systems.
- Digital multimeters and network analysers.
- Current indication and monitoring equipment.
- Protection relay installations.
- Manufacturing and process-control facilities.
- Commercial and infrastructure power distribution systems.
