🔍 Key Concepts

• Idle electrical equipment and what happens when it is not energized for a long time • How insulation systems in motors/generators can deteriorate over time • Which conditions most affect dielectric strength (ability of insulation to resist breakdown)

💭 Think About

• Think about what happens to equipment sitting in a warm, possibly humid machinery space over weeks or months without running. • Which option would most directly reduce the insulation resistance between windings and ground? • Consider which problem would most likely cause a dangerous fault the first time you re-energize the machine after a long idle period.

✅ Before You Answer

• Identify which choices affect insulation resistance versus just mechanical condition. • Ask yourself which effect can happen just from storage/standing idle, even if the machine was in perfect condition when it was shut down. • Consider which condition is commonly checked with a megger test (insulation resistance test) before putting idle equipment back in service.
