150 KV PORTABLE IMPULSE GENERATOR
|Abstract:||The advances made within the realm of Electrical Engineerin*- during the twentieth century have been phenomenal. Tremendous advances and increased power demand spurred more and more power transfer at longer distances and hence at higher voltage. In India 400 Ky lines are already in operation and it is estimated that up to the end of sixth five. years plan about 900 Km length of 400 XV line willl be In operation, Thus with large rtomr rof high voltage and extra high voltage transmission lines being constructed all over the country as part of large power developments programme, expensive electrical equipments are put into service, Consequently it has become ne-cessary to ensure that such equipments are capable of withstanding the overvoltage met with in service due to lightning and switching transient. In order to simulate these over voltage conditions all the power transmission and distribution apparatus are frequently subjected to high voltage impulse or surge tests which are performed by the impulse generator. Thus impulse generator is used to study the insulation Certdin behaviour under a conditions which the apparatus is likely to encounter. '"eats are also made with higher impulse voltage than normal iiorking voltage to determine factor of safety over working conditions. Impulse generator simuet Es-the • li ghtn g and .sj1tch1ng impulses for research and development purpose.|
