Lightning and surge protection - basic principles
www.mtl-inst.com1.2 Surge protection devices (SPDs) Electronic equipment can be protected from the potentially destructive ef-fects of high-voltage transients. Protective devices, known by a variety of names (including ‘lightning barriers’, ‘surge arrestors ‘, ‘lightning protection units’, etc.) are available.
