Answer:
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
Explanation:
The parameters given are;
Number of primary winding, [tex]N_p[/tex] = 50 turns
Number of secondary winding, [tex]N_s[/tex] = 150 turns
Voltage in secondary winding, [tex]V_s[/tex] = 450 volts
Voltage in primary winding = [tex]V_p[/tex]
The relation between [tex]N_p[/tex], [tex]N_s[/tex], [tex]V_s[/tex] and [tex]V_p[/tex] is as follows;
[tex]\dfrac{V_p}{V_s} = \dfrac{N_p}{N_s}[/tex]
Which gives;
[tex]V_p = \dfrac{N_p \times V_s}{N_s}[/tex]
From which we have;
[tex]V_p = \dfrac{50\times 450}{150} = 150 \ volts[/tex]
The primary voltage = 150 volts.
