Study Notes

a) Transformers come in various types: a) Constant Voltage Transformer (CVT), b) Variable Voltage Transformer (VVT), c) Auto Transformer, d) Distribution Transformer. b) Induction principle is used in Transformers. c) Spiral core Transformer, Oil immersed, Spiral Self-Cooled Transformer, and Dry Type Transformer are different transformer types. d) Transformers up to 25 kVA size are selected for implementing various cooling methods. e) Static-Induced VVB (Statically Induced Voltage Variable Transformer) is an example of a VVT. f) Cross-over, Sandwich, Helical, and Disc are different types of windings in a transformer. g) If the secondary voltage is greater than the primary voltage, it is a Step Up Transformer. h) Buchholz Relay is a protection relay used in oil immersed transformers. It won't operate if gas bubbles are not formed due to faults. i) An alarm is given when faults happen, and it's installed in oil immersed transformers. Gas bubbles are formed inside the transformer due to faults. j) The relation between input (IA) and output (IB) current and input (VA) and output (VB) voltage in a transformer is: VA.IA = VB.IB.
