최신 ICP Programs API-SIEE 무료샘플문제 (Q77-Q82):
질문 # 77
According to ANSI C57.12, the tank pressure under rated conditions of sealed transformers shall not exceed what value?
- A. Four atmospheres
- B. One atmosphere
- C. Two atmospheres
- D. Three atmospheres
정답:B
설명:
The correct answer isA. Forsealed transformers, ANSI C57.12 places limits on the pressure that can develop inside the tank during operation under rated conditions. The purpose of this requirement is to ensure that normal thermal expansion of the insulating liquid and internal atmosphere does not create excessive mechanical stress on the tank, cover, gaskets, welds, or fittings. In practical terms, the standard intends that the sealed tank construction safely contain the internal pressure developed in service without distortion, leakage, or failure.
From an API source inspection standpoint, this requirement is important because the inspector must verify that the transformer design, fabrication, and routine testing demonstrate the integrity of the tank and sealing system. This includes reviewing vendor drawings, design data, pressure-related test records, weld quality, and evidence that the tank can withstand expected service conditions. If internal pressure were allowed to rise excessively, it could compromise gasket sealing, create oil leaks, or damage the enclosure, all of which would affect reliability and acceptance.
Therefore, among the listed choices,one atmosphereis the correct maximum value stated in this context.
질문 # 78
Which of the following is listed as a typical transformer inspection point in the guide?
- A. Rotor bar balance check
- B. Ventilation fan blade pitch adjustment
- C. Verification of PCB content labeling
- D. Impeller alignment
정답:C
질문 # 79
What is the purpose of labeling the temperature range on electrical equipment used in a Class I hazardous area?
- A. To verify the process temperature and the equipment temperature have the same Class I rating
- B. To ensure that the equipment maximum temperature does not exceed the autoignition temperature of the specific gas or vapor to be encountered
- C. To ensure the equipment is compatible with the other Class I devices
- D. To verify the maximum process temperature does not exceed high levels
정답:B
설명:
The correct answer isB. In aClass I hazardous location, flammablegases or vaporsmay be present. The purpose of the equipmenttemperature marking, often expressed through atemperature class or temperature code, is to ensure that under normal operation and specified abnormal conditions the equipment'smaximum surface temperaturewill remainbelow the autoignition temperatureof the hazardous atmosphere present. This prevents the electrical equipment itself from becoming an ignition source.
This is a fundamental hazardous-area protection concept used when inspecting electrical equipment nameplates, certifications, and compliance markings. The inspector must verify that the marked temperature classification is suitable for the gas group and ignition characteristics of the service environment. The marking is not intended simply to match process temperature, compare with other Class I devices, or confirm general high-temperature limits. Instead, it is specifically aboutignition preventionin the presence of flammable vapors.
Within API-aligned source inspection practice, this falls under verification ofequipment markings, nameplates, code compliance, and hazardous-area suitabilityduring manufacturing review and inspection.
Therefore, the temperature range or temperature classification label is used to ensure the equipmentwill not exceed the autoignition temperature of the gas or vapor present, makingoption Bthe verified answer.
질문 # 80
Machine vibration measurement using non contacting probes are taken:
- A. on the frame during residual unbalance with the feet unclamped.
- B. on horizontal, vertical and the axial directions on the baseplate.
- C. on the shaft at 1.2 times the running speed.
- D. on horizontal, vertical and the axial directions on the bearing housings.
정답:D
설명:
The correct answer isD. In rotating electrical equipment,non-contacting probesnormally refer toproximity probesthat are mounted in or at thebearing housingsto monitorshaft relative vibration. These probes do not touch the shaft; instead, they sense shaft motion relative to the bearing housing. In practice, radial vibration is usually monitored in thehorizontal and vertical directions, and where applicable axial movement is also monitored using an axial probe arrangement. That makes option D the only technically correct choice.
The other options are not consistent with standard vibration measurement practice. Measurements taken on thebaseplateorframeare generally made with contact sensors such as accelerometers or velocity pickups, not non-contacting probes. Option B is incorrect because vibration is not defined as being measured "on the shaft at 1.2 times the running speed" as a standard probe location criterion. The API guide includeselectric motors over 500 HPamong its covered equipment categories and emphasizessource inspection and quality surveillance activitiestied to applicable standards, testing, and verification during manufacture.
질문 # 81
The Arc Flash PPE is required for:
- A. insulated cable examination with no manipulation of cable.
- B. work on control circuits with exposed electrical conductors below 120 VAC.
- C. voltage-testing in ac systems with work on energized conductors.
- D. removal of covers on properly installed wireways, junction boxes, and cable trays.
정답:C
설명:
The correct answer isC. Arc flash PPE is required when a task exposes a worker to the possibility of anarc flash hazard, especially when testing or working onenergized conductors or circuit parts.Voltage testing in AC systemson energized equipment is a recognized task that can place the worker within the arc flash boundary, because probes, tools, or inadvertent contact can initiate an arcing fault. For this reason, proper arc-rated clothing and related PPE are required whenever the task assessment identifies arc flash exposure.
The other options describe tasks that are generally considered lower risk when performed under normal conditions. Work oncontrol circuits below 120 VACdoes not usually present the same arc flash risk level.
Removing coverson properly installed wireways, junction boxes, and cable trays is not automatically an arc flash task unless it exposes energized parts and abnormal conditions exist.Insulated cable examination with no manipulation of the cableis also typically not treated as an arc flash exposure task.
From a source inspection and electrical safety perspective, the key principle is thatPPE selection is based on exposure to energized conductors and the likelihood of initiating an arc event, which makesCthe verified best answer.
