    Protection efficiency of VAJRATM
    Protection class Protection efficiency Protection distance
    Class 1 max 98% 20m
    Class 2 max 95% 45m
    Class 3 80% to 95% 60m
  • First priority to set the protection efficiency when designing or installing a lightning protection facility.
  • After setting the protection efficiency, determine the protection class according to NCF17-102 Appendix B.
  • For accurate selection of a protection class, we need a protection class calculation sheet.
