10.2 Measurements and inspections
10.2.1 Visual test
Visual check is the most important and effective part of a switchgear test.
Electrical testing often does not disclose failures that become apparent on visual
inspection. A visual check must be carried out before each electrical safety test.
Following items should be checked:
- Wiring connection points,
- Protection covers, housings,
- Inscriptions and markings especially that related to safety,
- Cables (layout, radiuses, isolation),
- Switches, regulators, lamps, keys,
- Electrical and mechanical protection devices (barriers, switches, fuses, alarms),
- Technical documentation.
During visual inspection the measuring points for the electrical testing have to be
determined too.
Check that there are no signs of:
- Damage,
- Pollution, moisture, dirt that can jeopardize safety,
- Corrosion,
- Overheating.
