Wideband Electric Field Sensor

 

High Voltage Laboratory 

The High Voltage laboratory of the LRE (12.8 x 12 x 7.9 m) allows to perform tests under AC high voltage (partial discharge, up to 300 kV and dielectric loss factor), tests under standard lightning pulses and standard switching flashovers (up to 1 MV).

Main Equipment:  

  • Impulse generator (1.2 MV, standard lightning pulse and switching flashover).
     
  • Equipment for dielectric loss and partial discharge measurements, voltage divider, etc.

 

 

1.2 MV Impulse generator (lightning and switching)

 

Radiating systems for IEMI testing

(1) A sub-hyperband radiator consisting of a coaxial pulse forming (PFL) generator and a half impulse radiating antenna (HIRA). The measured system’s Vfar value (defined as the product of the electric field peak and the distance) is 27 kV. The radiated electric field rise time is about 400 ps in the far range.

 

(2) A mesoband radiating system consisting of a 433-MHz coaxial switched oscillator (SWO).
