An EHV line is loaded above its SIL (surge impedence loading). This line can be
considered:
a) A VAR source
b) A VAR load
c) A contingency violation
d) Over its STE (short term emergency rating)
Give this one a try later!
b) A VAR load
In cases where a data point ID fails for an extended period of time, the system
operator will manually update the value:
a) Every 15 minutes
b) Every 30 minutes
c) Every hour
d) Every 4 hours
,Give this one a try later!
b) Every 30 minutes
The PJM system is operated such that the contingency flow is less than the:
a) Warning rating
b) Emergency rating
c) Load dump rating
d) Normal continuous rating
Give this one a try later!
b) Emergency rating
When synchronizing isolated areas, which of the following conditions must be met?

2. Similar voltage
3. Matching load
4. Minimum phase angle difference
a) 1, 2, and 3 only
b) 1, 2, and 4 only
c) 1, 3, and 4 only
d) 2, 3, and 4 only

maximum load allowed with underfrequency relay protection enabled that can be
counted as dynamic reserve is:
a) 100 MW
b) 200 MW
c) 300 MW
d) 400 MW
Give this one a try later!
b) 200 MW
During the system restoration process, PJM can be expected to assume frequency
control when:

b) Two local control centers are interconnected
c) Three local control centers are interconnected
d) The control of an interconnected area is too burdensome for any one local control
center
