Selection Criteria for Lightning Arrester Capacitors
Improper capacitor selection can compromise protection system integrity. Consider these critical parameters:
  • Rated voltage: Should exceed system's maximum continuous operating voltage (Uc) by 20% (e.g., 520V+ for 480V systems)
  • Capacitance Value & Pulse Withstand: Select based on required discharge energy (100pF-0.1µF range) with capacity for nominal discharge current (20kA/8/20µs)
  • Low Equivalent Series Inductance (ESL): ≤20nH to prevent pulse response delays
  • Environmental Adaptability: IP68 sealing for coastal areas, altitude compensation (1% Uc reduction per 100m above 2000m), vibration-resistant designs for wind turbines
