medium voltage

Was wondering if any of you have taken this test for this certification? Been splicing for 5 years and looking to get this certification. Thanks, Joe

Hi all, it has been bugging me for hours about how to calculate detuning inductor for a delta-connected power factor correction capacitor. The available parameters are: grid frequency f = 50 Hz, grid voltage Us = 22 kV, installed capacitive power is 2.7 MVAr, and the impedance of the detuning...

Hello, I'm looking for a class on distribution voltages. Power xfmers, diconnecting means, substations, etc. Any ideas? thanks Carlos
