State two main consumers of electricity transmitted at low frequency Calculate the primary voltage of a transformer if the primary winding is 50 turns and the secondary winding is 150 turns with 450 volts.

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, = 50 turns

Number of secondary winding, = 150 turns

Voltage in secondary winding, = 450 volts

Voltage in primary winding =

The relation between , , and is as follows;

Which gives;

From which we have;

The primary voltage = 150 volts.
