ATP-EMTP modeling and performance test of different type lightning arrester on 132kv overhead transmission tower

摘要

Lightning and switching surges are the main causes of over voltages in power system. If any high voltage transmission tower stroked by lightning the insulation of the line and equipment connected to the power system can be damaged. Metal Oxide Varistor (MOV) type surge arrester might be used for protecting the transmission line insulations and equipment of the power system connected to the transmission tower. To simulate the dynamic properties of MOV type arrester several types of models are proposed. In this research IEEE model, Pinceti model and Fernandes model of MOV type surge arrester are simulated with ATP-EMTP transient simulator. A 900m single line of 132kv with three tower are designed and simulated with ATP-EMTP program and evaluate the performance of different models of lightning arrester for protecting the towers and transmission line from direct and indirect strike.
