Answer Posted / narendra sharma
11 kv cable resistance we can measure
Test voltage is 10 kv to 20 kv (RMS Value)
And time is depend on which voltage you are selected.
if 10 kv then time should be 120 sec..........
And resistance valu also going opposit to voltage..
if suppose volt is 10 kv then megger valu 2gomh, And if volt
20 kv and valu 1gomh then cable is ok both are same valu....
