Answer / arpit sood
an important test is the tan delta test or the dissipation
factor test
This is carried out with the help of an automatic scherring
bridge to measure the capacitance of the insulation
this is a measure of the integrity of the insulation or the
life expectancy of the transformer
the value of the dissipation factor should be more than or
equal to 0.7

During the testing of Electrical Equipment the test cables should not touch the equipments. For that testing engineers use to cotton rope to hang the cable from measuring Equipment to testing equipment terminal. Please explain the technical reason for this practice.
when current lags behind voltage how does it affect the circuit.In other words what is the significance of lagging current?
Will it be OK to connect a 5MVA 33/6.6kV Ynd11 Transformer to a Star connected Motor. Or on other words connecting a Delta to a Star. I have another 30MVA 33/11 Dyn11 and would it be practical to convert it to Dd0 consequently converting the Voltage Ratio to 33/6.35kV Dd0.
