3D & 2D Solid insulators conductivity characterization: Epoxy resin, XLPE, silicone, etc.
Current measurement leakage relating to time and controlled ambient environment
Characterization of solid insulators using 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 and data acquisition on PC
Temperature and humidity regulation system
Enhanced safety conditions while running the HVDC Conductivity test.
Minute current leakage measurements up to +/-40kV DC for solid insulator (in the order of 10-13A)
Simultaneous measurement for up to 4 samples: time saving and guaranteed same test conditions
Measurement in a closed and controlled environment
Gas nature: vide, air, N2, SF6 and g3
Pressure: 0 to 10 bar rel
Temperature: 20°C 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 dielectric properties can be studied rapidly, saving time.
