New SMIGHT Grid2 Gateway Plus integrates short-circuit indicators
SMIGHT, a leading provider of digitalization solutions for low-voltage networks, is expanding its portfolio with the SMIGHT Grid2 Gateway Plus. The new hardware component enables the connection of short-circuit indicators for the first time, combining measurements in medium and low voltage.
To locate short circuits and ground faults in the medium voltage, distribution network operators use short-circuit indicators (KSA) in local network stations. To ensure rapid fault clearance, it is crucial that the fault information is made available quickly and digitally. This allows fault repair teams to drive directly to the affected stations, reducing downtime.
Connection and communication
With the SMIGHT Grid2 Gateway Plus, compatible short-circuit indicators in local network stations can now be connected directly via an integrated Modbus RTU interface. An adapter is available for relay contact devices.
Fault information is transferred asynchronously to the SMIGHT Cloud. The optional SMIGHT Control Center Communicator enables direct, standard-compliant integration into the medium-voltage control system via IEC 60870-5-104 for seamless integration into existing control center processes.
At the same time, the SMIGHT Grid2 Gateway Plus enables the integration of low-voltage measurements from SMIGHT Grid2 sensors. This gives distribution network operators both fault information from the medium voltage and transparency about the load situation in the low voltage outputs with just one installation in the local network station. Medium and low voltage are thus brought together in a common solution for the first time.
Blackout-proof communication via 450 MHz
In addition to public LTE, the SMIGHT Grid2 Gateway Plus also supports the 450 MHz radio network. This frequency offers excellent coverage of open areas and buildings and is blackout-proof, meaning that communication continues to function reliably even during prolonged power outages.
Every SMIGHT Grid2 Gateway Plus comes equipped with active LTE communication and a pre-configured 450 MHz-capable SIM card as standard. This means that 450 MHz communication can be activated remotely for each local network station at any time as required. This creates maximum flexibility for future requirements. SMIGHT handles the procedural and commercial aspects. SMIGHT thus makes this fail-safe communication technology accessible to every distribution network operator.
Medium and low voltage at a glance
The Gateway Plus enables complete local integration of all relevant measurement data from a local network station. In addition to the low-voltage measurements from the SMIGHT Grid2 sensors, measurement data from the medium voltage, temperature measurements, and door contacts are now also recorded and transmitted.
The Modbus RTU interface transfers currents and voltages from short-circuit indicators and transformer measuring devices such as Kries IKI 50 and Janitza UMG 96RM/RM-E to the Gateway Plus. The selection of compatible devices is constantly being expanded and will in future also cover devices from the manufacturers Horstmann, PQ Plus, and Jean Müller.
The Gateway Plus also offers an integrated digital input for door contacts and PT100 temperature sensors.
“With the Gateway Plus, we are consistently expanding our solution to include the medium-voltage level,” explains Oliver Deuschle, Managing Director of SMIGHT GmbH. “This gives distribution network operators a comprehensive network overview, which significantly speeds up fault clearance.”
