True/False

Proper voltage results in greater efficiency of generators and other power facilities, hence greater revenue
True False

               begins at the generating stations, at the source.

True/False

Generating stations produce power with synchronous generators that are capable of adjusting voltage by themselves
True False

Synchronous generators produce the bulk of our power.
These generators are commonly operated at nominal             

True/False

Raising the field voltage increases the output voltage and VAR.
Lowering the field voltage has the opposite effect
True False

True/False

If the output voltage is too high, equipment damage may occur. If the output voltage is too low, the generator may fall out of synchronism with the Power System
True False

The two major types of banks used for voltage control at receiving stations are:

The tap changers operate using a              principle much like a step-type feeder voltage regulator. This stepping device usually operates in oil

Synchronous condensers are normally connected to the           of main power banks

True/False

In general, VAR should be supplied as close to the point of need as possible
True False

True/False

Most step regulators have a neutral plus 16 5/8% steps up and 16 5/8% steps down. This provides a total of 33 different settings
True False

The Line Drop Compensator senses resistance and reactance of both the            and the           

                  provide VAR close to the load for the greatest efficiency

True/False

Pole-top capacitors are often found on feeders near the load center.
True False

True/False

The scale to the right of zero is marked "+" indicating power or VAR flow out from the station bus. The scale to the left of zero is marked "- " indicating power or VAR flow to the station bus
True False

True/False

On a bank, "+" indicates that power or VAR flow is from the high voltage to the low voltage side of the bank. Conversely, "-" indicates that power or VAR is flowing from the low voltage side of the bank to the high voltage side.
True False

Any malfunction in voltage control equipment that prevents the
equipment from maintaining voltage schedules is              trouble.

True/False

Increasing the field voltage raises voltage and increases VAR.
Decreasing the field voltage lowers voltage and decreases VAR
True False

True/False

While 34.5kV capacitors are usually bus connected, 4.8kV capacitors may be connected to either a bus or a bank.
True False

The effect of switching on a 5 MVAR capacitor is as follows:

You should check voltage regulators for automatic operation. Do this by

You should attempt to make repairs such as changing fuses. Report failures to proper authorities who will have emergency repairs made. These reports may be to:

True/False

Increasing the field voltage raises voltage and increases VAR.
Decreasing the field voltage lowers voltage and decreases VAR
True False

True/False

Increasing the field voltage raises voltage and increases VAR.
Decreasing the field voltage lowers voltage and decreases VAR
True False

True/False

When an inoperative regulator is found, check the fuses or thermal circuit breakers
True False
