A Distribution Arrester is a high-performance surge protection device designed for installation on overhead power lines to safeguard transformers, insulators, and other distribution equipment from transient overvoltages caused by lightning strikes and switching operations. What controls it: Arrester performance depends on MCOV, rated voltage, residual voltage, TOV withstand, energy duty, grounding quality, and lead. In this configuration, the arrester is protecting the two insulators at the top of the tower fairly well but offers virtually no protection for the distribution transformer located some 5 m below. It prevents continued flow to follow current to ground and it is capable of repeating these functions as specified per ANSI standard C62. An arrester does not absorb lightning or.
