Why Is Negative Impulse Applied During Testing? For Oil immersed transformers the test voltage is normally of Negative polarity because this reduces the risk of erratic external flash over in the test circuit. 1.2μs is for front time (T1) to reach at least 50% of the full impulse voltage level. What is the significance of

What Are The Applications Of Impulse Current Generator? The main application fields of impulse current testing are: Arresters and Varistors (elements or complete systems). Lightning protection elements (for buildings, components of communication and distribution networks). Vehicles (cars, bus, trucks, trains) and aircrafts. What are the various applications of impulse voltage generator? The major application of
