[akmal]

Hi,

Could any one please help me with the following questions:

a) A test is to be carried out to confirm the correct phase sequence throughout the installation.

i) State three points on the installation where the phase sequence must be confirmed to show that the correct phase sequence has been maintained.

ii) State why it is necessary to confirm that the correct phase sequence has been maintained.

iii) State the instrument to be used to confirm phase sequence when testing with the supply off.

iv) State the instrument to be used to confirm phase sequence when testing with the supply on.

If any one can kindly answer any of the questions, it will be very appreciated.

Thanks
