Accepted Answer

A "Hot-Cold-Hot" test ensures that a multi-meter is functioning properly and the circuit is at zero potential.

Question 2

Cooling system leaks should be corrected because they may lead to electrical shorts and _______.&#10;A) over heating of components&#10;B) corrosion of electrical connections&#10;C) loss of coolant&#10;D) All answers are correct

Accepted Answer

Cooling system leaks can lead to a variety of issues such as over heating of components, corrosion of electrical connections, and loss of coolant, which can all cause further damage to the vehicle if left unchecked. Thus, all answers are correct.

Question 3

Inspection of control console electrical connections should include an approved LOTO procedure before begining work.

Accepted Answer

Inspection of any electrical connections, including control console electrical connections, should always include an approved Lockout/Tagout (LOTO) procedure for safety reasons.

Question 4

The acronym DTA stands for Driving to Aggressively.

Accepted Answer

The correct acronym for aggressive driving is GTA, which stands for "aggressive driving to."

Question 5

A tower foundation rod &#34;strike test&#34; should be used to verify the exact tension level of each rod.

Accepted Answer

A tower foundation rod "strike test" is used to determine the location, depth, and condition of foundation rods, not the exact tension level. Tension levels are typically measured using a torque wrench.

Question 6

Cooling systems utilized with power electronics may be classified as two types: liquid and forced air.

Accepted Answer

Cooling systems utilized with power electronics can be classified as liquid or forced air.

Question 7

Wind turbine foundations are generaly rock anchor or granite types.

Accepted Answer

Wind turbine foundations are typically made from concrete or steel, and they can vary in design such as monopile, gravity base, suction bucket, or jacket foundations depending on the location and environmental conditions. Rock anchor or granite types are not standard terminologies for wind turbine foundations.

Question 8

Verification of wind turbine control system safety switches should be performed during each preventative maintenance cycle.

Accepted Answer

Verification of safety switches is a crucial aspect of wind turbine maintenance and should be performed regularly to ensure the safety of personnel and equipment.

Question 9

Inspection of DTA blind areas should be carried out with caution because there may be insects, snakes, or other wildlife that have taken up residence since the last PM activity.

Accepted Answer

This statement is true. It is important to proceed with caution when inspecting blind areas of DTA because there may be wildlife present that can pose a threat or danger to the inspector. This is why proper personal protective equipment (PPE) and safety procedures should be followed during the inspection.

Question 10

The first step in a DTA control console wire and power cable inspection process should include ________.&#10;A) washing the therminal strips&#10;B) an approved LOTO proceedure&#10;C) stopping for lunch&#10;D) hoisting all tools to the nacelle

Accepted Answer

The first step in any maintenance or inspection process should always be a proper Lockout-Tagout (LOTO) procedure to ensure the safety of the technicians working on the equipment. A is not necessary for an inspection, C is unrelated and D is not appropriate for this task.
