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
What safety measure should be taken before working on a capacitor?
Connect the capacitor to a power source
Discharge the capacitor completely
Bypass the capacitor
Ensure the capacitor is fully charged
what tool should be used when opening a fixed bank capacitor?
shotgun
hammer
capacitor check tool
load bust
