API-SIEE Exam Dumps - Source Inspector Electrical Equipment

The correct answer isA. Metallic shielding components in cables, such asshield tapes, drain wires, metallic braids, or similar conductive shielding layers, are connected to theequipment grounding system, commonly through anequipment grounding busbaror other approved grounding termination point. The purpose of this connection is to provide a low-impedance path for induced voltages, capacitive charging current, noise, and fault-related currents, while also helping reduce electromagnetic interference and maintaining personnel safety.

In source inspection and quality surveillance of electrical systems, correct shield termination is important because improper grounding can lead to noise problems, unreliable signal performance, unsafe touch potentials, or ineffective fault-current control. The inspector therefore checks that cable shields and associated metallic components are terminated in accordance with the approved drawings, cable schedules, and project grounding requirements.

The other options are incorrect. Aceramic insulatordoes not provide the required grounding path. Alow voltage connectoris too generic and is not the intended grounding termination. Atransformer center tapis a system neutral point, not the correct destination for cable metallic shielding. Therefore, the proper connection point is theequipment grounding busbar.

The correct answer isB. The inspection coordinator. In the API source inspection framework, the inspector’s role is to independently observe, verify, document, and communicate quality-related concerns through the established inspection reporting chain. When schedule pressure appears likely to compromise product quality, the issue must be escalated to theinspection coordinator, because that person manages inspection execution, communication flow, and coordination between the purchaser, supplier, and inspection function. This keeps the inspector independent and ensures the concern is addressed formally rather than informally.

The other options are less appropriate. TheMaster Scheduleris responsible for planning and timing, not for controlling inspection escalation. Theshop QA Managerbelongs to the supplier’s organization, so reporting directly there could weaken the inspector’s independent reporting path. TheProject Managermay ultimately need awareness, but the normal and correct first notification route in source inspection administration is through the inspection coordinator. This approach aligns with API source inspection practice, where quality threats, deviations, and risks are communicated through designated inspection channels so that corrective action, hold points, and surveillance priorities can be managed properly.

The correct answer isC, Voltmeter. A voltmeter is the instrument specifically used to measure theelectrical potential difference, or voltage, between two points in a circuit. In electrical inspection and testing, voltage measurement is fundamental for verifying whether circuits, terminals, control panels, and equipment are energized at the correct values required by the design documents and equipment ratings. During source inspection and quality surveillance, understanding the correct use of test instruments is important because inspectors may review or witness electrical tests that confirm compliance with specifications and safe operating conditions.

The other options are not correct for this purpose. Anamp metermeasures current flow, not voltage. AWheatstone bridgeis primarily used for precise resistance measurement. Apotentiometeris generally a variable resistor or a device used in circuit adjustment and comparison methods, but it is not the standard instrument identified for routine measurement of potential difference in a circuit.

Therefore, when the question asks which instrument measures voltage between two points, the technically correct and standard answer isvoltmeter.

The correct answer isD. API RP 14FZ. This document is specifically intended for thedesign and installation of electrical systems on fixed and floating offshore petroleum facilitieswhere equipment may be located inunclassified areas and hazardous classified areas identified as Class I, Zone 0, Zone 1, and Zone 2. The key clue in the question is the use of theZoneclassification system. In API and offshore electrical practice,API RP 14FZaddresses the offshore application of the zone-based hazardous area approach.

By contrast,API RP 14Fis associated with offshore electrical system guidance using the olderdivision-basedclassification approach rather than the zone terminology.NFPA 70is the National Electrical Code and is broader in scope; it is not the specific offshore petroleum recommended practice asked here.IEEE 841relates to severe-duty squirrel-cage induction motors and does not cover complete offshore electrical system design and installation requirements.

For source inspectors, recognizing the correct governing document is important because inspection and surveillance activities must verify compliance against the applicable design basis, hazardous-area classification method, and purchaser specification.

The correct answer isA. UnderANSI C57.12transformer requirements, theaverage winding temperature rise above ambientis commonly limited to65°Cfor standard transformer designs. This limit is important because transformer insulation life is strongly affected by operating temperature. If the winding temperature rise exceeds the permitted value, insulation aging accelerates, reducing transformer reliability and service life. That is why temperature-rise testing is a key verification item during transformer manufacture and factory acceptance activities.

From a source inspection perspective, the inspector should verify that the transformer has been tested in accordance with the applicable standard, that the measured temperature-rise values are properly recorded, and that the results comply with the specified acceptance criteria. The average winding temperature rise is not the same as hotspot temperature, and it must be evaluated against the standard test method and rating basis. The other options are too high for the standard average winding rise value typically associated with ANSI C57.12. In API-aligned source inspection and quality surveillance oftransformers, confirming compliance of factory test results such as temperature-rise performance is an essential part of final acceptance. Therefore,65°Cis the verified answer.
