  • Ensure the energy coordination between the arresters type T1 and T2 or the arresters type T2 and T3, especially in the places where there is no adequate distance between the arresters.
  • If the energy coordination of surge protection is not observed, the excessive energy of passing impulse may cause a damage to the subsequent stage of the protective cascade.
  • If there is at least 5 m distance between two successive arrester types (in case of two successive arrester types in two different switchboards), it is possible to omit the decoupling element.
