Topic
Corona & Field Optimization
The challenge
High local field strengths cause corona: power loss, audible discharge, ozone formation and accelerated ageing of insulation.
Our approach
Nexums assesses the field distribution around connections, clamps and fittings and advises on corona suppression: geometry, corona rings and clearances. We review the underlying field calculations.
Standards framework
IEC 60071-1 · IEC 60815 · IEC 62271
Result
Recommendations to reduce local field strengths and corona within applicable limits.
FAQ
