Conversion and integration of measurands into substation automation, protection or SCADA process via RTU and/or via protocols IEC 61850 (for 7KG9662 variant), MODBUS TCP, IEC 60870-5-103 for further control and/or monitoring tasks
Monitoring of lower voltage levels and heavy load control, e.g. air conditioning and motors
Depending on the device type, the input circuits for voltage measurement are either designed as voltage dividers or they are galvanically isolated. Devices with galvanic isolation can be used without voltage transformers in the power systems IT, TT and TN. Devices with a voltage divider can also be used in these power systems; for IT power systems, however, an upstream voltage transformer is required.
