Question 1
When is the cable twist device activated?
Correct Answer:
When the control system fails to initiate the cable untwist function.
Explanation:
The situation tests a safety fallback mechanism: if the main control system fails to start the cable untwist action, the cable twist device kicks in to prevent the cable from twisting uncontrollably. This activation serves as a fail-safe, ensuring the system remains in a safe, controlled state even when the primary command isn’t executed. Wind speed thresholds and yaw positioning describe normal operating conditions or separate protective actions, not a fault that requires the twist device to engage. Maintenance is a manual activity, not an automatic fault-triggered response.
Question 2
If the resistance decreases while connected to a fixed voltage source, what happens to current?
Correct Answer:
The total current increases
Explanation:
With a fixed voltage, current follows Ohm’s law: I = V/R. If the resistance decreases while the voltage stays the same, the denominator gets smaller and the current increases. For example, at 12 volts, dropping resistance from 6 ohms to 3 ohms makes the current go from 2 A to 4 A. The same voltage pushes more charge per second when there’s less opposition. In real circuits, a power source may have some internal resistance and might not maintain the exact voltage under heavy load, but the basic idea is that lowering resistance at a constant voltage increases current.
Question 3
What depends on production?
Correct Answer:
Cloud cover percentage
Explanation:
Production is driven by environmental conditions, especially for solar or hybrid setups. When cloud cover increases, the sunlight that reaches the panels decreases, which lowers the energy produced. That direct link—more clouds means less production—means cloud cover percentage is the factor that production depends on. Other options describe outcomes or fixed requirements: income from a wind park follows production and market factors, the turbine warranty period is a contractual/specification item, and maintenance crew size is planned from broader operational needs rather than the immediate production level. So cloud cover percentage best explains what production relies on.
Question 4
How many times a year is maintenance scheduled on a modern wind turbine?
Correct Answer:
2
Explanation:
Maintenance is scheduled twice a year. This semi-annual cadence lets technicians carry out preventive checks and servicing of key components—blades, drivetrain and bearings, lubrication, hydraulic and electrical systems, brakes, and control hardware/software—before wear leads to failures. Doing maintenance about every six months helps catch issues early, keeps performance up, and minimizes downtime and costly repairs, which is why two times per year is the standard. Frequencies that are much lower can miss wear and lead to unexpected outages, while more frequent visits can add unnecessary downtime and cost.
Question 5
Which term describes current that flows in a single direction?
Correct Answer:
Direct Current
Explanation:
Direct current describes electric current that flows in one direction. In a DC circuit, the current maintains the same direction and polarity, like what you get from batteries or DC power supplies. This is different from alternating current, which reverses direction periodically. Pulsating current also flows in a single direction but varies in magnitude over time, typically arising from rectified AC, so it’s not a perfectly steady DC. No current means there is no flow at all, not a type of current. So, the term that best captures current moving in a single direction is direct current.
