Answer / gunasekaran
calculation is (2E+1)1.414
(11*2+1)1.414=23*1.414=32.52*.85=28kV already HV test done
at factory so we have applie only 85%of rated voltage
Is This Answer Correct ? | 12 Yes | 5 No |
Answer / solanki
i think it will be the around 23 kv for the 11 kv switchgear
bcz its take the calculation twice of rated switchgear voltage
