Final answer:
Terminal strips inspection in aircraft electrical systems includes checking for cleanliness, secure connections, proper labeling, and the absence of damage. Battery testers are used to verify the terminal voltage under load. Safety measures involve using isolation transformers and ensuring that plastic insulation on wires is intact to prevent shock and thermal hazards.
Step-by-step explanation:
During an inspection of the terminal strips of an aircraft electrical system, it should be determined that all connections are clean, secure, and properly labeled, and that there is no evidence of overheating, corrosion, or other damage. Using a battery tester, like those described in Figure 10.9, would ensure that the terminal voltage under load is within acceptable limits which is crucial for the safe operation of the aircraft electrical system. An electronics technician may use a high-power battery tester for large batteries, whereas a smaller device with a digital display would be used for smaller batteries.
Safety practices are crucial when inspecting electrical systems, and part of this includes using an isolation transformer when required, as it provides safety by isolating the user from the direct current that could cause an electric shock. Additionally, the plastic insulation on live/hot wires is important as it prevents both shock and thermal hazards, contributing to overall electrical safety.
