Space Charge Measurement System


Space Charge Measurement System for flat samples

Measurement system:

  • PEA (pulsed electroacoustic method) space charge measurement system.

Test specimen dimensions:

  • Flat test specimen plates with a thickness of up to 0.5 mm

Voltage load:

  • Voltages up to 30 kV DC

Measured values:

  • Space charge distribution over the thickness of the test specimen
  • Changes in space charge distribution over time
  • Change in space charge distribution over time and over the given load profile

Raumladungsmesssystem für Modellkabel

Measurement system:

  • PEA (pulsed electroacoustic method) space charge measurement system.

Test specimen dimensions:

  • Coaxial cable (model cable or medium voltage cable)
  • Insulation thickness: 3 mm - 15 mm
  • Outer diameter: 20 mm - 130 mm

Voltage load:

  • Voltages up to 100 kV DC

Measured values:

  • Space charge distribution in radial direction of the cable insulation
  • Changes in space charge distribution over time
  • Change in space charge distribution over time and over the given load profile
