Lightning protection for OHL when unprepared and un-calculated can lead to un-effective solution and highly expensive. On the 220kV OHL above, the TLA (Transmission line arresters) installed can cost up to 4000 USD / pc. When bought in excess or istalled at the wrong location, or the wrong phase, or in the wrong way, each mistake cost at least the price of the TLA and most likely the price of the trip that wont be prevented.
