2 & 3D Solid insulators – conductivity characterization: Epoxy resin, XLPE, silicone, etc.
Leakage current measurements within a defined timespan in a controlled ambient environment.
Characterization of solid insulators for DC voltage up to +/-40kV DC.
Laboratory & Equipment description
HVDC source: Fug +/-65kV DC with very low ripple
Keithley electrometer 6514, 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 Conductivity tests.
Solid insulator, leakage current measurements (1 minute interval), up to +/-40kV DC, ranging between 10-13A.
Up to 4 samples of insulating matter measured simultaneously allowing for time saving and guaranteed equivalent test conditions.
Measurement in a closed and controlled environment
Gas nature: void, air, N2, SF6 and g3
Pressure range: 0 to 10 bar
Temperature range: 20 to 100°C
Humidity within the gas
Fully computed 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 computed deployment of the platform, solid insulators dielectric properties can be studied rapidly, saving time.
