Abstract

Increasing applications of constantly developing electronic devices require delicate voltage and current protection. Although the electrical network is monitored continuously, undesired over currents and over voltages may occur on the distribution system due to failures. Most of the electronic switch gear is connected via surge protected power strips in indoor applications, where current protection is vital. Surge protected power strips are usually manufactured based on Metal Oxide Varistors (MOVs) which are capable of executing extremely non-linear current voltage characteristics. MOVs are employed for absorbing surges in the network and maintain acceptable current readings on the terminals of the power strip. Generally, MOV protected systems are analysed for transient surges within limited time durations. In this study, commercially available surge protected power strips are subjected to continuous over voltages in contrast to rated voltages and current and voltage characteristics are investigated. Besides, generated harmonics of surge protected power strips are analysed under extreme voltage conditions and maximum endurance of these strips are revealed.
