Total questions: 10
Worksheet time: 10mins
Regulators act as protective equipment on the power system by:
controlling voltage levels to prevent damage to equipment
increasing the current flow in the system
disconnecting the power supply during normal operation
reducing the frequency of the power system
A lineworker must make sure of which of the following before bypassing a regulator?
That the regulator is de-energized
That the bypass switch is closed
The regulator is in neutral
That the voltage is at maximum
Why is poor power factor a problem?
It increases energy efficiency
It reduces the load on the system
It causes higher losses and increased electricity bills
It improves voltage regulation
Capacitors help correct poor power factor by:
Increasing the circuit resistance
Providing leading reactive power to offset lagging reactive power
Decreasing the supply voltage
Converting AC to DC
What is the difference between fixed and switched capacitor banks?
Fixed capacitor banks are always connected to the system, while switched capacitor banks can be connected or disconnected as needed.
Fixed capacitor banks can be switched on and off, while switched capacitor banks are always connected.
Both fixed and switched capacitor banks are always disconnected from the system.
Fixed capacitor banks are used for voltage regulation, while switched capacitor banks are not used for this purpose.
What are differences between legacy capacitors and smart capacitors?
Legacy capacitors lack advanced features, while smart capacitors have monitoring and control capabilities.
Legacy capacitors are more expensive than smart capacitors.
Smart capacitors are less efficient than legacy capacitors.
There are no differences between legacy and smart capacitors.
What is the process for disconnecting a capacitor?
Why is shunting important for capacitor storage and transportation?
To prevent charge buildup and accidental discharge
To increase the capacitance of the capacitor
To reduce the physical size of the capacitor
To improve the efficiency of energy storage
What things should you look for when inspecting a capacitor?
Check for bulging or swelling.
Look for leaking electrolyte.
Inspect for burnt or discolored areas.
All of the above.
A lineworker can check to see if a regulator is in a neutral state?
