Connection of short-circuit and ground fault indicators from the medium voltage system

SMIGHT Grid2 Gateway Plus+ (1)

In order to reliably locate short circuits and ground faults in medium voltage systems, distribution network operators use short circuit and ground fault indicators in local network stations. The decisive factor here is not only the detection of the event, but above all its rapid and digital availability.

With the SMIGHT Grid2 Gateway Plus, fault information is transmitted directly from the local network station and integrated into the digital network view. This gives you an expanded network view across medium and low voltage – as a basis for faster fault localization and more efficient fault clearance.

Faster to the right station

Error information is transmitted as an event and can be integrated directly into existing processes, optionally via the control center connection. This
speeds up error localization and reduces search trips.

Medium and
low voltage at a glance

The Gateway Plus can consolidate measurement data from a local network station: In addition to low-voltage measurements from SMIGHT Grid2 sensors, information from the medium-voltage level and other signals can also be recorded and transmitted.

Communication even in emergencies

In addition to public LTE, the SMIGHT Grid2 Gateway Plus also supports the 450 MHz radio network. This provides an option for fail-safe communication—for situations where reliable transmission is crucial.

This is how it works

Connect

Short-circuit and ground fault indicators are connected to the SMIGHT Grid2 Gateway Plus in the local network station. Integration is carried out directly via the existing interface, or via a suitable adapter in the case of relay contact devices.

Transmit events

Detected short circuits or ground faults are automatically recorded digitally as events and transmitted to the SMIGHT IQ Cloud. The fault information is then immediately available for further processing and analysis.

Optional: Leitstelle integrieren

Optional: Integrate control center The SMIGHT Control Center Communicator integrates fault information into the medium-voltage control system via IEC 60870-5-104 – for use exactly where operational decisions are made.

SMIGHT Grid2 Gateway Plus+ (1)

The Gateway Plus expands the role of the local network station as a data node: It enables the local integration of relevant station information and transmission via LTE or optionally 450 MHz.

Technical facts:

  • Modbus RTU for connecting compatible devices
  • Event-based transmission of error information
  • Optional: Control center connection via IEC 60870-5-104 (via SMIGHT Control Center Communicator)
  • Communication: public LTE and optional 450 MHz (remotely activatable per station, incl. prepared SIM)

Application scenarios

In addition to integrating short-circuit and ground fault information, the Gateway Plus can also record other station signals—such as door contacts or PT100 temperature sensors—and thus make additional operating information available digitally.

  • Fault clearance in medium voltage: Make fault information digitally available, locate it more quickly, and target it specifically
  • Standardized control center processes: Use fault information directly in the control system
  • Future-proof communication: Optional 450 MHz communication for increased availability

Questions about Gateway Plus

The selection of compatible devices is constantly being expanded. We will be happy to provide you with details in a current compatibility list.

No. Error information can be provided as an event in the SMIGHT IQ Cloud. Control center integration is optional.

LTE is active by default; 450 MHz can be activated remotely per local network station if required.
