WITH DETAILED VERIFIED ANSWERS

A transmission line is operating with a voltage phase
angle different of 30 degrees between the sending
Vs and the receiving bus Vr. If the receiving end
load is suddenly increased, the voltage phase angle
difference will be? - ANSWER-The phase angle will
increase. When load is increased phase angle will
increase.
A load has a power factor of 0.9 lagging. If the load
draws 100 MVA, what is the MW draw? - ANSWER90 pf= mw/mva
The high side of a delta-wye connection transformer
is connected to a power system with 199 kV L-G
high side voltage. What is the voltage across the
delta winding of the transformer? - ANSWER-Vl-l=
square root of 3 times Vl-g 1.73x191= 345kV
If a transmission line is carrying 400 MW and 300
MVAR what is the MVA? - ANSWER-3-4-5 triangle

The prime mover is the component of the generator
that creates the rotational force. In a typical coal
fired steam generator what component spins the
rotor? - ANSWER-Turbine
Reactive reserve response during a disturbance is
best obtained from which devise? - ANSWERSynchronous condensers
For two identically constructed transmission lines
where Line A is 150 miles long and line B is 15 miles
long, if both lines are lightly loaded? - ANSWER-A
produces more reactive power than B.
Lightly loaded transmission lines essentially behave
like? - ANSWER-Shunt Capacitors
You receive an alarm that indicates low oil pressure
on an underground transmission cable. SCADA
shows the pressure is continuing to drop. What is
the first step you take to protect the line? -
ANSWER-Isolate the line
Computer simulations show that for a 100 MW
schedule from Bus A to Bus B, 63% of the schedule

will flow on other parallel paths. What is the
3
distribution factor for the scheduled path? -
ANSWER-63%
Which statement best describes how reactive power
