The operating speed of a protective relay is dependent on:
* Spring Tension
* Armature core air gap
* Rate of flux built up

This was originally a 'not question'. This list is not necessarily conclusive. It's simply the 'incorrect' answers to the 'not question'. According to IEEE C57.106, which test is recommended for routine acceptance of new, unprocessed oil from a supplier for use in circuit breakers?
ASTM D877
[Standard Test Method for Dielectric Breakdown Voltage of Insulating Liquids Using Disk Electrodes]

Meter Sockets and meter disconnect switches should generally be connected on what side of a service disconnecting means?
The line side
NFPA 70-2017 Article 230.82(3)
https://www.electricallicenserenewal.com/Electrical-Continuing-Education-
Courses/NEC-Content.php?sectionID=40.0
This was originally a True/False statement question. The answer stated that the load side is wrong. The reference above seems to imply that meter sockets and meter disconnect switches should generally be connected on the line side.
Know NFPA 70
What size neutral resistor would be required to limit the fault current of a 13,800-480Y/277V 1500kVA Transformer to 5A?
55.4
Know Ohm's Law. 277 V / 5A = 55.4 ohms
I believe that since this is dealing with the neutral, Line-Neutral voltage (277 V) should be used in the formula. 5 A on the line will also be 5A on the windings since the transformer configuration is a Wye configuration. I also believe that the impedance of the transformer is negligible in this calculation since it isn't mentioned in the question and presumably would only limit the fault current further.
Correcting the power factor of three-phase loads normally involves adding (capacitance, inductance) in (series, parallel)
capacitance in parallel
