Aşırı gerilim koruma modülleri olan önleyici sistemler elektrik / elektronik sistemleri ve cihazları gerilim darbelerinin neden olabileceği hasarlardan korur. Oluşan aşırı gerilimler önleyici sistemler sayesinde kademeli olarak nominal voltaj seviyesine indirilir.
Etkin bir koruma sistemi tasarlanırken elektrik alt yapısına uygun projelendirme ve modül seçimi yüksek önem arz eder.
