Characterisation of solid insulators under DC voltage up to +/-40kV DC ;
2 & 3D Solid insulators – conductivity characterisation: Epoxy resin, XLPE, silicone, etc.
Leakage current measurements within a defined time span in a controlled environment.
Laboratory & Equipment description
HVDC source: +/-65kV DC with very low ripple.
Electrometer, range from 2fA to 2mA.
Relay system with PLC controller including data acquisition on a PC.
Temperature and humidity regulation system.
Enhanced safety conditions when running the HVDC long-term conductivity tests.
Solid insulator, leakage current measurements ranging between 10-13A and 2×10-3A, under DC voltage up to +/-40kV
Up to 4 samples of insulating matter measured simultaneously, saving time and guaranteeing equivalent test conditions
Measurement in a closed and controlled environment
Gas nature: vacuum, air, N2, SF6 and g3
Pressure range: 0 to 10 bar
Temperature range: 20 to 100°C
Humidity within the gas: RH%, ppmv
Fully controlled measurements using the PLC control unit: DC voltage, temperature, gas humidity
Thanks to low noise of the HVDC generator, extreme high sensitivity of the current measurement, ability to perform simultaneous measurements for up to 4 samples, and the automatic process of the platform, solid insulators’ dielectric properties can be studied rapidly, saving time.
