Transformers<\/strong><\/p>\n

Core: The core is made of high quality imported cold rolled grain oriented (c.r.g.o) silicon steel
\nlaminations of m4 grade\/0.27mm thickness and is coated with magnesium silicate phosphate
\ninsulation on both sides. To fully utilise the grain orientation of the lamination, the ends of the limbs
\nare mitred and stacked together by over lapping the lamination in pairs, which will reduce the no-
\nload losses and thus the power required for magnetizing the core. The core will be rigidly clamped
\nwith positive locking device to ensure adequate mechanical strength to support the windings
\nand also to prevent shifting of laminations during transport and further to reduce vibrations to a
\nminimum during operations.<\/p>\n

Winding: The windings are made of rectangular or round sections of electrolytic grade copper
\ncovered with several layers of age resisting insulation paper or enamel coating of high dielectric
\nstrength. Coils are wound with adequate tightness to sustain from external or internal mechanical
\nstresses. Sufficient cooling channels\/ducts between windings are also provided. Transportation of
\nconductor turns are taken care on L.V. windings whenever necessary.<\/p>\n

Automatic Stabilizers<\/strong><\/p>\n

Due to addition and subtraction of loads, the supply terminal voltage fluctuates. Voltage fluctuation
\ncan be controlled manually or automatically by various methods. The safest and surest and most
\naccurate of them all is servo controlled method which is widely accepted. Major advantage of having
\na servo controlled voltage stabilizer is that the right from the transformer and variac to the sensing
\ncontrol circuit.<\/p>\n
