High Voltage Busbars
AMPHENOL AUXEL offers an optimized approach for high voltage low inductive interconnections: use of specific material, low inductive design with respect of creepage distances and efficient control of partial discharge…
traction converters, wind energy converters, MV power conversion systems, SiC (Silicon Carbide power switching components).
PD (partial discharge) is a localized dielectric breakdown of a small portion of an electrical insulation system that is under high voltage stress, which does not bridge the space between two conductors.
- Partial Discharge phenomenon is intrinsically linked to compact high voltage systems
- Partial Discharges within solid insulation systems are not visible
- The partial discharge test helps to predict future performance and reliability of busbar
- Typically partial discharge should be below <10pC according to IEC 61287 at defined voltage Vtest
AMPHENOL AUXEL designs laminated busbars able to withstand high level partial discharges (used in high voltage systems)
