9) Field best practices (lessons from experience)

  • Log everything: serial numbers, test values, torque readings, and photos on installation day.
  • Baseline data: capture insulation and contact resistance at commissioning to compare later.
  • Label parts/switch positions clearly to reduce human error.
  • Environment-proofing: apply conformal coating or surge protection where coastal or heavy pollution exists.
  • Train crews on specific manual torque values and permitted lubricants — generic lubes can degrade dielectric materials.
  • Use calibrated test equipment and keep certificates current.
