Reliable Current Measurement for High-Current Systems
Current transformers allow high primary currents to be measured by converting them into a lower proportional secondary current suitable for electrical instrumentation. The Lovato DM37T2500 provides a standard 5 A secondary output, enabling compatible meters and power monitoring devices to measure currents in high-capacity electrical distribution systems without carrying the full primary current through the measuring instrument.
The DM37T2500 solid-core design is particularly suited to new switchboard and busbar installations where the primary conductor can be routed through the transformer during assembly. Its large opening, high measurement accuracy and industrial construction make it suitable for power monitoring, energy management and electrical distribution applications.
Typical Applications
- High-current industrial switchboards.
- Busbar current measurement systems.
- Low-voltage power distribution installations.
- Energy meters and power monitoring equipment.
- Power quality and electrical network analysers.
- Industrial plants and manufacturing facilities.
