Experiments On Single Phase Transformer

EXPERIMENTS ON SINGLE PHASE TRANSFORMEROMEGA 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 1f 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.OBJECTTo perform open circuit test of 1Φ TransformerTo perform short circuit test of 1Φ TransformerTo determine efficiency and regulation of 1Φ TransformerVerification of transformation ratio of Transformer.FEATUREThe board consists of the following built-in partsMoving Iron AC portable Voltmeter / : Housed in bakelite case with knife edge pointer & anti parallax mirror scale of 140mmAmmeter/Wattmeter: Length spring controlled movement having accuracy class 1.0Two moving iron AC Voltameter 0 - 300 V.One moving iron AC Voltmeter 0 - 75 V.Two moving iron AC Ammeter 0 - 10 Amp.One moving iron AC Ammeter 0 - 100 mA.Two Wattmeter single phase dynamometer type Multirange current coil 5/10 Amp. Potential coil 75/150/300 Volt.Wattmeter single phase dynamometer type current coil 0.5 Amp.
