OTLM weather station

OTLM weather station is used to accurately measure weather conditions along the overhead line (OHL). Measurements from the weather station and OTLM device are then used for ampacity calculations.

Key features:

  • Automatic data collection
  • Configurable sample package interval (3-30 minutes)
  • Automatic data transfer using GPRS
  • Local data archiving during periods of communication failure
  • Remote reconfiguration, upgrade
  • Alarms
