Reliable High-Current Measurement for Electrical Monitoring
Current transformers such as the Carlo Gavazzi CTD8H20005AXXX allow high AC currents to be measured by converting the current flowing through the primary conductor into a proportional lower secondary current. The resulting 5 A signal can be connected to compatible energy meters, multifunction meters, power analysers and electrical monitoring equipment without requiring the full primary current to pass directly through the measuring instrument.
The CTD-8H series is designed for industrial electrical distribution systems where substantial busbars and high primary currents need to be monitored. Its solid-core construction, class 0.5 measurement accuracy, large rectangular aperture and standard 5 A secondary output make the CTD8H20005AXXX particularly suitable for main switchboards, distribution panels and energy monitoring installations requiring measurement of currents up to 2000 A.
Typical Applications
- High-current electrical energy metering systems.
- Main switchboards and electrical distribution panels.
- Industrial power analysers and multifunction meters.
- Building and industrial energy management systems.
- Large busbar monitoring installations.
- Industrial load and electrical consumption monitoring.
