Single Phase Transformer (Open, Short, Efficiency And Ratio) Omega Type ES-333:
OMEGA TYPE ES- 333 Experimental setup has been designed Specifically to study the performance of transformer and determine open circuit test, short circuit test, efficiency and voltage regulation of 1 ø Transformer. The setup consist of voltmeters, ammeters, wattmeters, load resistors variac and transformer.
The setup is complete in all respect and requires no other apparatus. Practical experience on this setup carries a great educative value for Science and Engineering students.
OBJECT
- To perform open circuit test of 1 ø¸ Transformer.
- To perform short circuit test of 1 ø¸ Transformer.
- To determine efficiency and regulation of 1 ø¸ Transformer.
- Verification of transformation ratio of Transformer.
