ELECTROTECHNOLOGY SINGLE PHASE TRANSFORMER EXPERIMENT AIM To determine the approximate equivalent circuit of a single-phase transformer. OBJECTIVE To write up a lab report that will determine the equivalent circuit of a single-phase transformer, using open load test, short circuit test and the load test. EQUIPMENT * TecQuipment electrical machines teaching unit NE8010 or NE8013 * B-phase transformer (EMTU-TT01) * Feedback electronic wattmeter * Multi-range moving-iron ammeter * Instrument voltage transformer THEORY AND INTRODUCTION Transformers are used all over the world to step-up and step-down electricity. The transformer is one of the most commonly used electrical devices. The reason the transformer is so popular is because they range in size from 240V to well over 240kV, stepping -up and stepping-down electricity all over the world. Another reason they are so popular is because they are very efficient items that are very reliable and require little maintenance. Everytime we turn on an electrical item in our house, the electric used to run the device has...
