Abstract

Electrical transmission and distribution systems will face the transient overvoltage, the amplitude that may exceed the peak value of a normal system voltage by a large amount. This transient overvoltage will occur due to two reasons that are by lightning strikes or by switching. Overvoltage that occurs due to lightning are called an external overvoltage and independent of system voltages. Switching overvoltage is an internal overvoltage that occurs due to the switching operations such as circuit breaker switching and always related to the system operating voltage. The purpose of this project is to perform a specific study on a high voltage impulse test in terms of: high voltage impulse test definition, types of impulse testing, configuration, characteristics of impulse test, wave shapes and high voltage impulse testing standard. An impulse test will then be performed on a selected consumer product in order to study the effect of the test, first by a simple simulation by using MULTISIM software, and then by a practical lab test. The practical lab test is done to determine the insulation strength on a various condition of the insulation surface.
