Huawei Updated H19-260_V2.0 Exam Questions and Answers by sultan

The exact extract states that the synchronous adjustment camera increases reactive power output when grid voltage rises and absorbs reactive power when grid voltage drops. That operating logic is reversed, so the correct answer is False. A synchronous condenser, or synchronous compensator, is indeed a synchronous machine without a mechanical driven load and is used for voltage and reactive power support. However, when grid voltage drops, the system should supply or generate reactive power to support voltage recovery. When grid voltage rises, it should absorb reactive power to prevent overvoltage and stabilize the system. The statement in the question says the opposite: it claims reactive power output increases when voltage rises and is absorbed when voltage drops. That contradicts normal reactive-voltage regulation behavior. Therefore, despite the opening definition being mostly correct, the reactive power response described in the statement is incorrect.

The exact extract asks which activity is not a key activity of the SQA role as a “continuous improvement pusher.” The correct answer is A. Option A belongs more naturally to the “safety and quality result guardian” role because it focuses on safety and quality results, product delivery and O & M outcomes, target-oriented planning, and preventing safety or quality accidents. A continuous improvement pusher is different: the focus is on building improvement mechanisms, teaching teams to use scientific safety and quality engineering methods, identifying recurring improvement points, and promoting regular closed-loop improvement. Options B, C, and D directly describe continuous improvement behavior: establishing mechanisms, guiding analysis methods, creating incentives, commending improvement work, and organizing improvement-point identification. Therefore, option A is not wrong as a safety-and-quality activity, but it is not the best match for the “continuous improvement pusher” role. It is assigned to a different SQA role category.

The exact extract asks how the traditional solution ensures PV DC-side security. The correct answer is A, B, C. A fuse is a traditional protection component used to interrupt excessive current on the DC side. A DC combiner box is also a traditional PV-side component that combines strings and normally contains fuses, surge protection, and DC isolation/protection elements. A manual disconnect switch is another traditional method for isolating PV strings or DC circuits during maintenance or fault handling. These three options are directly associated with DC-side protection and isolation. Option D, AC switch, is not correct because it belongs to the AC side of the inverter output, not the PV DC side. The question is specifically about the security of the PV DC side, so AC-side switching cannot be counted as a DC-side protection method. Huawei’s newer C & I safety materials contrast these conventional protections with intelligent DC-side disconnection and rapid active protection.

The exact extract says: “Quality requirements are explicit requirements, excluding implied requirements.” The correct answer is False. In quality management, a requirement is not limited only to what is explicitly written in a contract, specification, or checklist. Requirements also include needs or expectations that are generally implied, customary, obligatory, regulatory, or necessary for intended use. ISO 9000 terminology defines a requirement as a need or expectation that is stated, generally implied, or obligatory. Therefore, quality requirements include explicit requirements and implied requirements. For example, a customer may not explicitly state that equipment should be safe, reliable, and compliant with local electrical standards, but those expectations are still quality requirements. Excluding implied requirements would create a narrow and unsafe quality-management approach. In Huawei Smart PV project and partner quality management, SQA must consider explicit technical requirements and implied quality expectations tied to safety, reliability, and customer acceptance.
