Short Circuit Tests and Transformers

What ESP means ? , is it Electrostatic Precipitator & Are you looking for S/ckt test for Transformers for High voltage Transformer-rectifier sets , please clarify?

Generally, S/ckt test is as usual.

Do not understand question!

Despite I don't know what the abbreviation "ESP " stands for ,,, however according to my knowledge about the transformers in general , I can tell you that the purpose of short cicuit test of a transformer is to determine the full-load cupper loss as well as equivalent resistance & equivalent reactance referred to metering side …. Practically in this test , the terminals of secondary winding "usually of low voltage winding " are short-circuited by a thick wire or strip or even through ammeter .. then variable low voltage is applied to the primary through an auto-transformer or voltage divider ,,, bear in mind that the applied voltage to the primary is gradually increased until you get the full "rated" load current (via ammeter ) of the metering side ….by getting the current ,voltage & power mesures , you can calculate the equivalent resistance , equivalent reactance and the full-load cupper loss by applying some equations .......

I hope that this'll help you........
