Introduction<\/strong><\/h4>\n

Drop out surge arresters are MOV based devices that are designed to protect against
\nthe damaging effects of spikes and transients caused by lightning, utility switching, isolation arching, electrical motor cycling, or any other sudden change in the electrical
\npower flow on incoming AC power lines. Lightning damage, is responsible for a large
\npercentage of over-voltage occurrences, these are either direct strikes to a line or
\ninduced voltages onto the line. (strikes within 40m of a line). Drop out surge arresters prevent flashover between phases, prevent damage to poles
\nand protect transformers from lightning damage and surges. Live Line Arresters can
\nbe intelligently placed on lines in problem areas where equipment is consistently
\ndamaged. The placing of Drop out surge arresters has proven to be more cost effective than
\nimproving the insulation of poor performing lines. A spent Drop out surge arrester can
\nbe exchanged for a new unit within minutes with the aid of a link stick and with the
\nsystem energized. This eliminates unnecessary outages and lost revenue for the
\nelectrical utility.<\/p>\n
