In a shutdown, the applications and targeted components during visual inspections of internal systems are varied. However, the requirements of a videoscope unit for these inspections are not. Brightness, high-quality images, and portability are all crucial for an effective remote visual inspection. The nature of these inspections is to search for mechanical and structural defects (i.e., turbine blade defects [cracks, pitting, missing material], weld integrity, valve functionality, etc.). The three aforementioned videoscope requirements— brightness, high-quality images, and portability—provide inspectors the ability to find these critical defects during an inspection. They also enable further investigation and accurate measurement for reliable reference against the relevant standard.
