Power components
A current transformer converts a high electrical current into a lower measurable value that can be processed by an energy meter or analyser.
A split-core current transformer can be opened and placed around an existing cable. This usually means that the wiring does not need to be completely disconnected.
A Rogowski coil is flexible and can be placed around larger conductors or cable bundles. It is often used when little space is available or large currents need to be measured.
A transducer converts a measurement value into a standardized signal that can be read by a controller, PLC, display, or management system.
A sensor measures a specific value. An I/O module collects signals from sensors and devices or sends commands to the installation.
Yes. The exact possibilities depend on the available connections, communication protocols, and structure of the installation.
Energy meters
An energy meter measures electrical energy consumption or energy production. Depending on the model, voltage, current, power, frequency, and other electrical parameters can also be measured.
A MID-certified meter may be required when the measurement data is used for settlement or billing. The exact requirements depend on the application.
An energy meter is primarily focused on consumption and electrical base values. A power quality analyser also records more extensive information about the quality and stability of the electrical installation.
That depends on the electrical installation and the maximum current. For larger powers, an indirect measurement with current transformers is often used.
Yes. When the meter has the correct communication interface, data can be sent to a local system, web server, or energy management platform.
Yes, we assist in the selection of the meter, current transformers, communication, and integration into the desired application.
