New Sensor for electric field strength

new sensor for measurement of fields & voltages: safe, contactless, mobile, reliable

  • miniaturized sensor for measurement of static and low-frequency electric fields
  • non-contact measurement of direct and alternating voltage (DC, AC) 
  • for high, medium and low voltage
  • for mobile and stationary applications
  • without grounded components – floating ground
  • no on-site calibration required – can be used pre-calibrated
  • robust, durable, easy to handle, safe

Level of innovation

  • uniquely practical measuring principle 
  • first public presentation of a prototype – world premiere!

Applications

  • warning of high-voltage – e.g. for workers in transformer stations as well as on power lines, for cranes, lifting platforms, airplanes, helicopters, drones etc.
  • warning of electrostatic charging, prevention of dust explosions (e.g. flour, shavings) 
  • display of residual charge (e.g. in high-voltage lines that have been disconnected from the grid)
  • monitoring of real exposure limits for electric fields (HVDC, HVAC, hybrid lines, transformer stations, etc.)
  • warning of thunderstorm formation and lightning 
  • display of charge state for batteries and accumulators – contactless
  • object identification

Target groups

  • power industry 
  • aviation, medicine, robotics, civil engineering, mechanical engineering 
  • meteorology 
  • manufacturers of safety devices and safety equipment – e.g. ESD protective equipment 
  • manufacturers of measuring devices
