Direction: The following item consists of two statements, one labelled as ‘Statement (I)’ and the other as ‘Statement (II)’. Examine these two statements carefully and select the answer using the code given below:
Statement (I): In HVDC systems, the dc voltage should be as low as possible and the rectifier control angle α should be as high as possible.
Statement (II): Control of dc voltage is exercised by the rectifier and inverter control angles α and γ respectively.
1
Both Statement I and Statement II are individually true and Statement II is the correct explanation of Statement I
2
Both Statement I and Statement II are individually true but Statement II is not the correct explanation of Statement I
3
