How to avoid partial discharges?
Avoid air gaps in the insulation system:
- Insulation bonded to the conductor
- Limit the size of the air gaps (< 10 microns)
- Fill the “singular” areas with insulating material
Limit the intensity of the electric field, where there would be air gaps:
- Increase space between conductors will increase global inductance (not acceptable)
- Avoid peak effect, round edges
- Reduce relative permittivity level of the insulation system
- Reduce electric field intensity

- Partial discharge resistant insulation (incorporation of inorganic material)
V.I.L.B. technology will provide answers to these constraints…
