Accurate Three-Phase Energy Monitoring
Transformer-connected energy meters such as the ABB A44 213-100 enable electrical consumption to be measured in installations where current and voltage transformers are used to scale the primary electrical quantities to levels suitable for the meter. Configurable transformer ratios allow the displayed and communicated values to represent the actual primary-system energy usage.
The A44 series combines energy metering with detailed electrical instrument values and communications capability. M-Bus connectivity enables meter information to be collected remotely by compatible building-management and energy-monitoring systems, while the integrated infrared interface provides additional communication possibilities.
Typical Applications
- Industrial three-phase energy monitoring.
- Commercial building electrical distribution systems.
- Switchboards and electrical control panels.
- CT/VT-connected energy metering installations.
- Building-management and energy-management systems.
- Sub-metering and energy consumption monitoring.
