5. 0:10to let's grow up
6. 0:12let's start
7. 0:13[Music]
8. 0:15core it is made up of soft iron or
9. 0:18silicon steel materials
10. 0:20the iron core is made of thin metal
11. 0:22strips and insulated from each other by
12. 0:25insulating varnish coating the thickness
13. 0:28of the transformer core laminations
14. 0:30is usually in the order of 0.25
15. 0:33millimeters to 0.5 millimeters
16. 0:37core clamps steel frame is used to hold
17. 0:41all the laminations of the core
18. 0:45so that during working of transformer
19. 0:47the laminations remain braced against
20. 0:49heavy electromagnetic forces
21. 0:51produced due to varying flux in the core
22. 0:56core insulation the core is insulated
23. 0:59from the grounded mechanical structures
24. 1:11primary winding or low voltage winding
25. 1:13is always placed inner side of core
26. 1:16windings are electrically insulated from
27. 1:18each other through insulation material
28. 1:21copper and aluminum both conductors are
29. 1:24used in transformer windings
30. 1:26the winding also insulated by insulation
31. 1:29material
32. 1:38insulation
33. 1:45high voltage winding or secondary
34. 1:47winding is placed above the low voltage
35. 1:52winding
36. 1:54[Music]
37. 2:07[Music]
38. 2:14main tank cover
39. 2:21cover is fitted with the core frame
40. 2:33low voltage bushing or connector the
41. 2:36transformer bushing is an insulating
42. 2:38structure
43. 2:39that facilitates the passage of a
44. 2:41current carrying conductor
45. 2:43through the grounded tank of the
46. 2:47[Music]
47. 2:48transformer
48. 2:58[Music]
49. 3:05high voltage bushing or connector
50. 3:21conservator tank it is a small tank
51. 3:24which is used in high power transformers
52. 3:27it is connected above the main tank of
53. 3:29the transformer
54. 3:30it has a cylindrical shape main tank and
55. 3:33conservator tank are connected to each
56. 3:35other through a pipe
57. 3:40breather breather as a device which is
58. 3:43used for breathing of transformer
59. 3:45its mean air goes in or out from the
60. 3:48transformer
61. 3:48with the help of a breather
62. 3:52buckholt's relay it is placed over the
63. 3:55connecting pipe
64. 3:56that runs from the main tank to the
65. 3:58conservator tank
66. 3:59the buckholtz relay senses the faults
67. 4:02occurring within the transformer
68. 4:10explosion vent it is used to expel
69. 4:12boiling oil in the transformer during
70. 4:15heavy internal faults
71. 4:16in order to avoid the explosion of the
72. 4:18transformer
73. 4:19the oil rushes out of the vent
74. 4:24main tank it is a steel box transformer
75. 4:28core is placed inside this tank
76. 4:30windings and other helpful devices are
77. 4:33placed inside this tank
78. 4:34it is filled with insulating oil mineral
79. 4:39[Music]
80. 4:40oil
81. 4:42[Music]
82. 4:44radiator the radiator of the transformer
83. 4:47accelerates the cooling rate of the
84. 4:48transformer
85. 4:50thus it plays a vital role in increasing
86. 4:53loading capacity of an electrical
87. 4:55transformer
88. 5:01[Music]
89. 5:08[Music]
90. 5:17[Music]
91. 5:25finally oil filling when voltage goes up
92. 5:29or down
93. 5:29the temperature of the transformer's
94. 5:31windings increases
95. 5:33oil is used to cool down the condition
96. 5:36it acts as an insulator between the
97. 5:38windings
98. 5:39it increases the resistance between them
99. 5:41and avoids short circuit
