About this document
2.4 The Surge Protection Device (SPD) : Principle by mahmoud12122012 is a document available to read on EtoBox.
The document discusses surge protection devices (SPDs) which are used to protect electrical power supply networks, telephone networks, and communication and automatic control buses from overvoltage. SPDs are connected in parallel on the power supply circuit of loads to protect them. When a transient overvoltage occurs, the impedance of the SPD decreases so surge current is driven through it, bypassing sensitive equipment.
