[@premkumarr4522]

Excellent explanation sir

[@thilsathbanu5378]

It's very easy to understand sir... Because of u teaching in practicallly... Nice sir..

Thank you...!

[@tharatharu9968]

But how to find the watt value with normal watt meter. Shall we take watt meter reading directly as core loss in oc test and copper loss in sx test???? Pl reply sir

[@learnelectricalconcepts5210]

Error may come if we use normal watt meter. Please try to use LPF meter for OC test and UPF meter for SC test👍

why oc test on lv side and sc test on hv side ?

[@learnelectricalconcepts5210]

HV side must be open ... because we can easily set the LV side voltage(115V) using auto transformer... and LV side must be shorted... because current will be lesser in HV side (8.7A)than LV side current (17.4A)..Therefore auto transformer loading (source loading) effect is avoided... Please consider meter selection in addition to this... Tq..

Sir, if we connect upf wattmeter in OC test, what will happen on power reading?

[@learnelectricalconcepts5210]

We cant get the accurate no load power value...

Sir please explain about static characteristics of jfet

Sure...

[@sivasankar4028]

Sir, wheather primary side open or secondary side open in OC test? Pl . Explain again..

[@learnelectricalconcepts5210]

HV side should be OC... LV side should be SC... you no need to look like Primary and Secondary...
