MAIN PARAMETERS TO TAKE INTO ACCOUNT TO PREPARE FOR AN APPLICATION SIMULATION 

The measurement of electric fields requires a lot of precaution to ensure valid values. Unlike the measurement of magnetic fields or voltages which are quite well controlled, the measurement of an electric field involves the understanding of the comprehensive performances of the measuring device, the data acquisition system and of course, the application.

THE UNDERSTANDING OF THE APPLICATION

In one hand, the customer should have some basic knowledge of the expected values to obtain like:

• Min and max values of the electric fields

• Bandwidth of interesting signal

• Single pulse signal or repetitive signal

• Shape of signal

The customer should also know the way to handle the measurement:

• Measurements of the E-fields in time-domain (with an oscilloscope) or in frequency-domain (with a spectrum analyzer) or both

• The performances of its acquisition devices (oscilloscope or spectrum analyzer)

• The various possible settings to improve the performances of the measurements

• The constraints of the measurement inside the applications (EMC, vibrations of the measurement support, temperature variations…)

THE PERFORMANCES OF EOSENSE AND EOPROBE SYSTEM

The eoSense converter provides a laser to the eoProbe that measures the field. The eoProbe reflects the laser back to the optical electronic converter including the signal information. The converter converts the laser information into an analogue electric value proportional to the electric field at any time.

• The general performances of the eoProbe are mainly defined by:
• The bandwidth (approx. 10 Hz up to approx. 50 GHz)
• The sensitivity (depending on the model of the eoProbe)
• The medium of the eoProbe (for air, liquids or gazes)

Example of Application Simulation Output Signal

Whatever the application, the frequency response of the eoProbe is generally the one presented here. This curve, based in an internal simulation tool, does not represent the certified performances of the eoProbe but it is just representing a typical measurement of an electric field

Measurement of E-fields in Medium and high voltage (HV) Magnetic Fields. Normal Configuration:

• eoSense Converter LF (1, 2 or 3 channels. Bandwidth 40Hz~30MHz, 30dB internal amplification)

• eoProbe air probe type with 1 mm or 5 mm of crystal, longitudinal or transverse. Depends on application and investigations.

• Testing: Repetitive pulses or single pulse (partial or total discharges). usually time domain but frequency domain may be sufficient.

Measurement of Electric Fields Emitted by Antennas. Normal Configuration:

• eoSense Converter depends on frequency. Is always with an internal amplifier.

• eoProbe Usually 5 mm crystal longitudinal or transverse
