SUMMARY

The appropriate size of HT cable from an 11 kV feeder line to energize a 500 kVA transformer through an SF6 breaker is critical for safety and efficiency. Due to the high voltage and power levels involved, it is essential to consult with a certified electrical engineer or local power company for accurate specifications. Attempting to determine cable size without professional guidance poses significant risks, including electrical hazards.

PREREQUISITES
  • Understanding of high voltage (HV) electrical systems
  • Knowledge of transformer specifications, specifically 500 kVA
  • Familiarity with SF6 circuit breaker technology
  • Basic electrical safety protocols
NEXT STEPS
  • Research the standards for HT cable sizing for 11 kV systems
  • Learn about the installation requirements for SF6 circuit breakers
  • Investigate local regulations regarding high voltage installations
  • Consult resources on electrical engineering best practices for transformer connections
USEFUL FOR

Electrical engineers, technicians involved in high voltage installations, and anyone responsible for the safe operation of transformer systems.

I sincerely regret not giving the answer you hope, but 11kV and 500kVA are not for a layman, and I won't help you killing yourself.
My apologies.

My apologies.

The layman should inquire through his local power company or electrical engineer, and have a someone certified to hook it all up. One wrong connection and your toast.
