  • SMA01 Surge & Arrester Monitoring
  • 4ca209de-9bc2-4b82-89ec-66400de516b8.png

Key features

  • Wired or wireless solution. Outdoor device: IP67
  • Solar supply & external supply versions
  • Lightning surge events and record
  • Durable device: glass window, stainless steel, aluminum, HDPE
  • Cable diameter up to 16mm

Scope of application 

 The SMA01 is meant for diagnostic of Line Lightning Protection Devices (LLPD) or External Gapped Line Arresters (EGLA) in service, record peak currents, historical data, number of events, cumulative charges discharged by the equipment.
It allows aging qualification to reach higher accuracy in order to optimize reliability and expenditure.
With a communication range of 50m, the IEEE 802.11 b/g/n standard allows the user to connect remotely & safely. SMA01 Surge Monitoring can be installed easily on ground conductors.
The monitoring display can be mounted back, or strapped up to 10m from the measurement point. The device complies to the IEC 62561. Thanks to its IP67, housing, rugged materials, and self-power, the SMA01 is suitable for outdoor and hazardous atmospheres.
Power supply is ensured through Li-ion batteries and solar panels. Optional DC power supplied can also be arranged.
