ASENS

ASENS

Highly Accurate Acoustic Sensor for Partial Discharge Localization .

KEY FEATURES

  • Built in pre-amplifier
  • Narrow band resonant sensor with highest signal to noise ratio
  • Simple and rugged sensor
  • Easy to use, light weight
  • Plug and play connections
  • Highly sensitive

RM’s advanced acoustic measurement has an additional advantage of possessing better- signal to noise ratio for real-time applications. To avoid the damage to high voltage equipment, detecting and locating PD is crucial both in industries and utilities. Acoustic waves are measured by ASENS, and the AE System will identify the real PD and their location based on ML/Time Difference of Arrival (TDOA) algorithm with the highest percentage of location accuracy to fault location. 

  • Oil Filled Reactors
  • Oil Filled Transformers
  • Gas Insulated Switchgears and Gas Insulated Lines
  • PD localization with multiple sensors
  • High noise immunity for online partial discharge detection
  • Integrated amplifier for better SNR
  • Significant time saving through fast localization of the fault
  • Quick and easy application
  • Good return on investment
