The cosine of the difference in phase angle between voltage and current is:
正解：A
解説：
The correct answer isA, power factor. In AC electrical systems, the phase relationship betweenvoltageandcurrentis an important indicator of how effectively electrical power is being used.
Thecosine of the phase angle differencebetween voltage and current is called thepower factor.
Mathematically, power factor expresses the ratio ofreal power, which performs useful work, toapparent power, which is the total power supplied to the circuit. When voltage and current are in phase, the cosine value is 1 and the power factor is unity. When they are out of phase due to inductive or capacitive effects, the power factor becomes less than 1.
From a source inspection and quality surveillance standpoint, understanding power factor is important when reviewing electrical test data, motor performance, transformer loading characteristics, and system efficiency information.Real poweris measured in watts,apparent powerin volt-amperes, andmhois a unit of conductance, so none of those terms define the cosine of the phase angle itself. Therefore, the correct technical term for this cosine relationship ispower factor.

The highest voltage rating on a piece of medium voltage equipment is the:
正解：C
解説：
The correct answer isA, basic impulse level. On medium voltage equipment, thebasic impulse level BILis the highest voltage-related rating normally associated with the insulation system. BIL represents the ability of the equipment insulation to withstand a specified high-voltage impulse, such as a lightning surge or switching surge, without failure. It is therefore a dielectric withstand rating that is higher than the equipment's normal operating or system voltage and is used to define insulation coordination for the equipment.
The other choices are not the best answer.Nominal voltageidentifies the intended system operating voltage class, but it is not the highest voltage-related rating.AC high potentialandDC high potentialare test voltages used during dielectric testing, not the principal nameplate rating that defines the equipment's insulation impulse withstand capability. In source inspection of switchgear and other medium voltage assemblies, the inspector verifies that the equipment ratings, including voltage class, insulation level, and test records, agree with the purchase specification and applicable standards.
Because BIL expresses the highest recognized insulation withstand rating among the listed options,Ais the verified answer.
質問 # 96
Which edition of industry codes and standards applies to the equipment being inspected?
正解：C
解説：
The correct answer isD. The edition specified in the engineering design. In API source inspection practice, the inspector does not choose whichever code edition appears newest or most convenient. The applicable requirements are the ones defined by thepurchase order, engineering design documents, project specifications, approved drawings, and referenced codes and standards identified for that job. Source inspection is a verification function, so the inspector must confirm compliance against thecontractual and technical basis of designestablished for the equipment being manufactured.
This is important because different editions of the same standard may contain different rating rules, test requirements, construction details, or acceptance criteria. If an inspector were to apply the latest edition without project authorization, that could create conflict with the approved design basis and lead to incorrect acceptance or rejection. Likewise, the edition found at the point of use or supplied by the inspection agency is not automatically controlling unless it matches the project's specified design basis.
Therefore, for inspection and quality surveillance of electrical equipment, the governing edition is theedition specified in the engineering designand related contract documents.
質問 # 97
According to API 541, totally enclosed machines TEFC, TEPV, TEWAC, and TEAAC are equipped with which of the following?
正解：D
解説：
The correct answer isA. Under API 541,totally enclosed machinessuch asTEFC, TEPV, TEWAC, and TEAACare required to have alow-point drain. This requirement exists because enclosed motors can accumulatecondensation or moistureinside the housing due to temperature changes, shutdown periods, ambient humidity, or cooling system operation. If that moisture is not removed, it can degrade insulation, promote corrosion, contaminate internal parts, and shorten motor life. The low-point drain provides a controlled path for accumulated liquid to escape from the lowest part of the enclosure.
The other options are not universally required for all these enclosure types. Aheat exchanger cooling fanmay apply only to certain cooling arrangements, not to every totally enclosed machine listed.Bearing RTDsmay be specified for monitoring on many large motors, but they are not the defining common feature identified by this question.Surge protectorsare auxiliary protective devices and are not the standard enclosure-related requirement here. In source inspection practice, the inspector should verify that the motor enclosure includes the requireddrain provisions, that they are properly located, and that they conform to the approved design and specification.
質問 # 98
Why should the dates for source inspection scheduled work process events such as the pre-inspection meeting, key inspection events and anticipated shipping date be identified in advance?
正解：D
解説：
The correct answer isA. In the API source inspection process, planned dates for events such as thepre- inspection meeting,key inspection points, witness or hold activities, and theanticipated shipping datemust be identified early so that everyone involved in the supply and inspection chain can coordinate their responsibilities. This includes the purchaser, supplier or vendor, source inspector, expediting personnel, quality representatives, and sometimes third-party test witnesses. Advance identification of these dates helps ensure that the right people, documents, and inspection resources are available at the right time and that critical manufacturing or testing stages are not missed.
OptionBsounds reasonable, but identifying dates in advance does not by itself guarantee that schedule and quality requirements will be met. OptionCis only part of the benefit, not the main reason. OptionDmay be a practical staffing advantage, but it is narrower than the overall project coordination purpose.
From an API guide perspective, source inspection is aplanned and coordinated activity, not a last-minute visit.
Therefore, the main purpose of identifying these dates early is toallow coordination with all project members involved in the activity.
