SPDs for Power lines are available for AC (Three phase and Single phase) & DC applications. International Standards recommend. Zone wise protection for power lines, i.e different types of SPDs shall be provided at various levels of the power system namely, the Main switchboard, sub switchboard, near the equipment etc,. To make the protection simple & effective we are offering a wide range of SPDs. Few common SPDs are detailed below.
