I know that calculation is normally how Volt Drop in a cable is determined, However my client has written this ' Actual Test ' requirement into the test specification.
If anyone has carried out sutch a test, without using PT's and recorders at each end of the cable, I should be most grateful...
The cable is supplying an 11kV 1200kw motor
The 'Actual Voltage Drop' is defined as the end to end drop in voltage under start and full running load conditions.
I have contacted cable manufacturers in UK,Saudi and Kuwait, all tell me that they don't actually carry out a VD test to determine...
I have to test the actual voltage drop in an 11kv cable, the cable is a 185mm2/cu/3core/xlpe/pvc, 1500mtrs long.
Has anyone carried out such a test and what equipment did you use??
