Scope
This Recommendation addresses the lightning protection of dedicated transformers used to provide electrical power for radio base stations (RBSs). It contains procedures for earthing@ bonding and direct lightning protection of the dedicated transformer@ including protection methods for the associated power lines@ requirements for surge arresters (medium voltage (MV) and low voltage (LV) arresters)@ and protection procedures for ancillary facilities. Transformers used for powering an RBS and other components (i.e.@ shared transformers) are not covered in this Recommendation. The lightning protection of these shared transformers is contained in [b-ITU-T K.111].
