OilQSens® Transformer oil testing

High performance and early detection for Transformer oils / insulating oils.

OilQSens® transformer oil testing

The all new OilQSens® monitors early changes in insulating oil constantly and online. The OilQSens® is an extension of our continued commitment to introduce new products in the field of testing and diagnostics. The OilQSens® consists of a sensor and a communication unit. The OilQSens® will be installed and operated in a bypass line at the device under test (mainly HV Transformers) .


OilQSens® performs the following measurements constantly:

  • Conductivity Ƙ
  • Permittivity εr
  • Temperature
  • Tan Delta TD (calculated)
  • Breakdown Voltage (calculated)
  • Water content (calculated)


This measurements will be conducted with an unmatched sensitivity and accuracy enabling users to analyse and identify problems at an early stage.
