Reliable Current Measurement for Electrical Systems
Current transformers such as the Carlo Gavazzi CTD-4X reduce high primary currents to a proportional and manageable secondary current for measurement equipment. This allows meters, power analysers, monitoring devices and energy-management systems to measure electrical loads without requiring the full conductor current to pass directly through the measuring instrument.
The CTD4X7005AXXX is particularly suited to higher-current distribution systems where a 700/5 A measurement ratio is required. Its Class 0.5 accuracy, solid-core construction and large conductor opening make it a dependable solution for switchboards, industrial control panels and energy-monitoring installations.
Typical Applications
- Industrial energy metering and monitoring systems.
- Electrical switchboards and distribution panels.
- Power analysers and multifunction electrical meters.
- Building energy management systems.
- Industrial machinery and control panels.
- Load monitoring and electrical consumption measurement.
