    With its current sensors, the ASTROSE system already offers a comprehensive range of available measured values around the conductor rope. This includes a highly accurate current measurement (+/-1A) as well as a voltage measurement (+/-1kV) with the derived quantities of phase angle and reactive power.

    With an overhead transmission line length of over 33,000 km, TEN Thüringer Energienetze GmbH & Co. KG is the largest distribution network operator in Thuringia. The company continuously deploys modern and efficient infrastructure to ensure grid stability and to meet the requirements of the associated grid expansion plan. As TEN is very interested in continuous monitoring of the overhead transmission line temperature, an ASTROSE pilot system will be installed in the Sömmerda area in autumn 2020. For validation and evaluation of the values measured by the wireless sensor nodes on the conductor, these values will be made available directly to the control center via the IEC60870-5-104 communication protocol.

  • For the qualification of the new generation of ASTROSE wireless sensors high voltage tests for the 380kV voltage level were carried out. The focus was on the dielectric strength of the entire system and the immunity to interference from partial discharges and transient processes such as lightning strikes or switching surges.
