LPL I + II
System: Three Phase TT / TN-S
MDB: Boundary of LPZ0 and LPZ1
SDB: Boundary of LPZ1 and LPZ2 if >100m away from MDB.
A lightning surge protection device prevents damage to electrical and electronic equipment from transient over-voltage events by blocking or redirecting surge current to the ground instead of passing through the equipment. In a well -designed system, it is important that for each building, both the incoming and outgoing circuits are protected by surge protection devices (where the cables enter and exit the building).
- Mains power supplies – including UPS
- Telephone lines
- Data communication lines
- Instrumentation, control, signaling lines
- Coaxial lines for CCTV, TV, & antenna cables
Field based electronic equipment also need to be protected.
