Transient surges resulting from lightning strikes and
switching operations cause the failure and destruction
of electronic devices. TVs, videos and DVD recorders, stereos

Using surge protection devices reduces downtimes of
devices and systems. To
prevent loss investments, relevant insurance-related
questions need considered. Under VdS Directive 2010, property
insurers require systems kWp more be
fitted with lightning protection and internal surge
voltage protection.2. Only protected
