🥳MY 2ND DAY IN THE INTERNSHIP 🥳
👆DRY TYPE TRANSFORMER 👆
as we know the dry type transformer generally consists of three phases the three windings in which two windings are damaged and the repair of providing of the dry type transformer will generally cost about ₹2.5 lakh rupees. that place we can generally get a new dry type transformer. so the decision has to be made by the customer on whether to buy a new dry type transformer or to generally repair the windings of the damaged dry type transformer.
👆OIL TYPE TRANSFORMER 👆
eventually they cannot take the decision at the sudden moment they might take the decision after sometime. and inspection is also done by the government Electricity Board company as how did the dry type transformer catch fire And how the windings have been burnt. generally the dry type transformer student catch fire and it is very important to know what the fault is in the dry type transformer. the winding pattern of the dry type transformer this comparatively different when compared to that of the oil type transformer. in the dry type transformer we can generally find the spacing between the windings that is generally in order for the proper air flow. interactive Transformer generally make use of copper windings covered with animal come for insulation purpose. the most important thing that we need to remember in a dry type transformer is the bushings are different when compared to that of the bushings of the oil type transformer. the size of the dry type transformer whole Transformer body is very much smaller than compared to that of oil type transformer. the main advantages of the dry type transformer is here we are not making use of any Transformer oil. but the maintenance cost is very much high in dry type transformer. one of the problem is that if the water is mixed with oil of the transformer then it creates a very huge problem that is either during the testing process we may not get the correct or exact values all the performance of the transformer may decrease instantly. the next question that arises is how to really find out as how the water is mixed with the Transformer oil this weekend generally find out either by means of the manure method that is generally by checking the oil with the hand is the oil quality is bad then we need to replace the all with the new Transformer on the vegetable oil. as we know that the current will generally flow to the water so it will affect the insulation how the Transformer windings. and the process generally involved in oil changing process is firstly we need to remove all the oil from the Transformer and we need to lift the Transformer windings by means of the hydraulic lift and let the Transformer windings be there in the hydraulic lift for many Har so that all the Oils will be generally wiped out generally fall in the Transformer tank. after sometime you can disappear in the Transformer tank as well the Transformer windings and then after removal of the oil from the Transformer winding we are going to place it in a Transformer oven. the transformer is generally kept in oven we need to generally keep it for either 12 hours or 24 hours. the Transformer oven we need to set up the temperature as well as in the control panel we can also see how many minutes it generally takes to generally complete the oil drying process. after the 24 hours we are going to do the different test on the Transformer windings to check the practical value with the theoretical value. and then only we can decide what to do next with that Transformer or to find out the fault in a transformer. generally we feel about 340 litres of Transformer oil of the vegetable oil in a transformer this both in a conservative oil tank as well as in the Transformer tank. hear the oil be used in a transformer tank it should not be a new all we can use the reused oil generally by transferring that oil into the oil filtration tank
and then again recycling it into a clean oil and then finding that oil into the Transformer tank. The cost of oil filtration machine varies from ₹60,000 to some ₹1lakh rupees depending on our requirements. for the recycling process of the oil we are generally having a separate machine or we generally quality oil filtration vehicle. if I generally wanted to know about oil filtration vehicle in simple words that is it generally consists of two valves, Oneness the inlet valve we will generally the dirty oil and the other is a outlet valve where we will get a clean oil, and all coming out of the outlet valve will be very hot. during starting the colour of the transformer all will be generally white aur pure white, and the oil is generally useless then it will be Radisson colour. the oil which cannot be used again is generally given to the scrap which can be used for mechanical purpose and for industrial purpose so on. the most important thing in the Transformer oil is the ingredients used in the Transformer oil is very dangerous to human health so the government is generally thinking thinking of making use of a pure vegetable oil for the Transformer oil in the upcoming future. we have come to the end of the section where in my internship today I learnt about the oil running process in a transformer and the step by step sequence what we need to follow during the oil changing process of the transformer and I'm very eager to learn many more things about the Transformer in in the upcoming days of my internship.
