Answer 2

1) a. Customers requiring AC electric power transmission for powering remote devices which may include a subsea transmission system where power is distributed to subsea devices

b. Customers that utilize commutator-type motors

2) The primary voltage is 150 volts

Step-by-step explanation:

The parameters given are;

Number of primary winding,
`N_p` = 50 turns

Number of secondary winding,
`N_s` = 150 turns

Voltage in secondary winding,
`V_s` = 450 volts

Voltage in primary winding =
`V_p`

The relation between
`N_p`,
`N_s`,
`V_s` and
`V_p` is as follows;

`(V_p)/(V_s) = (N_p)/(N_s)`

Which gives;

`V_p = (N_p * V_s)/(N_s)`

From which we have;

`V_p = (50* 450)/(150) = 150 \ volts`

The primary voltage = 150 volts.
