A 10 KVA transformer is rated 7200 volts primary and 120 volts
secondary. What is full load current? - ✔✔✔ Correct Answer >
10,000/120=83.3 primary
7200/120= 6
60 to 1 ratio
83.3/60= 1.38 secondary
What qualities are involved in OHM's Law?
What is electrical horsepower? - ✔✔✔ Correct Answer > Voltage,
current, and resistance
746 watts
, Pole steps should be spaced what distance apart? - ✔✔✔ Correct
Answer > 18"
At what angle does a lifting sling have the same weight stress as the
load being lifted? - ✔✔✔ Correct Answer > 30*
When paralleling two transformers, what should be checked to be sure
of satisfactory results? - ✔✔✔ Correct Answer > Polarity, impedance,
and voltage
A three phase transformer voltage is 66000/12470Y. Full load on high
side is 13.1 amps.
What are the amps on secondary?
What is the KVA capacity? - ✔✔✔ Correct Answer >
66000/12470=5.29
5.29x13.1=69.29 or
69.3amps secondary
12470x69.3x1.732
