For long-type arresters deliver more voltage to the earth while new type arresters supply more voltage through the air channel, and the old type of earth clamp arresters are connected to the conductor while the new type arrester has a 6 cm air gap and then a maximum distance of 8 cm between the conductor and Arrester. Therefore, the writing will discuss about "Installation of Lightning Arester of the old type with new type Lightning Arester (Sai20z) on network (SUTM) 20 kV".} }
