NLC Smart Grid Week 2 Quiz

Which of these is a valuable true fact about regulators?

• It can boost or buck line voltage on the LOAD side by a maximum of 7.5%

• It can boost or buck line voltage on the SOURCE side by a maximum of 10%

• It can boost or buck line voltage on the LOAD side by a maximum of 10%

• It can boost or buck line voltage on the SOURCE side by a maximum of 7.5%

What is the 'golden rule' when bypassing a regulator?

• Make sure the regulator is not on neutral before bypassing and removing

• Neutral is always first to make and also the first to break

• Always ohm out the regulator before and after usage

• Always make sure a regulator is on neutral before bypassing & removing.

Intentionally lowering system voltage is known as:

• Voltage drop rate (VDR)

• Conservation voltage reduction

• Ohms law

• Bypassing customer load.

What best describes the purpose of a capacitor?

• corrects power factor

• Creates induction which counteracts for the capacitive load

• counter acts power factor

• Creates a resistive effect which then creates the circuit to stay in phase

Why should you wait 5 mins when disconnecting a capacitor from the system?

• To let any watts customers were using bleed out of the line

• Less of a risk for lightning to strike while working on the line

• For the capacitor to discharge using its internal discharge resistor

• For the capacitor to shut down properly using its smart grid computer

An internal resistor is designed to discharge the line voltage to ___ volts.

• 50 volts

• 120 volts

• 25 volts

• 200 volts

How do you check for potential loss of integrity on capacitor while it is in service?

• Sent off for special testing

• A visual inspection from the outside

• A voltmeter

• Ohm the capacitor out.

How should you transport capacitors?

• Rigged to the belly of truck

• On the sides with foam padding

• Secured upright/terminals shunted

• Laying on the terminals.

What is the primary function of a voltage regulator in an electrical circuit?

• To increase the current flow

• To store electrical energy

• To decrease the resistance

• To maintain a constant voltage level

Which component is used to store electrical energy in an electric field?

• Transformer

• Resistor

• Inductor

• Capacitor
