Visual examination in electrical testing
Visual Examination is very important and often precedes electrical testing. Oftentimes it reveals major issues that may not have been found by testing alone.
In-service visual examinations and electrical testing are divided into three groups, operator checks, formal visual examination as well as a combined visual examination and electrical testing. There are no strict schedules to adhere to; however, several factors may influence how often these checks are done.
Intended use: Some pieces of equipment are used more often than others. Handheld equipment is manipulated and moved around more than a piece that is stationary. Equipment that is being moved regularly needs to be checked more frequently due to potential rough handling that can result in damage and early failure.
Surroundings: Equipment found on a construction site is more likely to become damaged as opposed to equipment in an office. Therefore, equipment in rugged environments need to be checked often.
Operators: Operator checks are important when it comes to equipment. If constant unreported abuse goes on, then testing of equipment will need to be performed on a regular basis.
By examining equipment employing operator checks, formal visual examination and combined visual examination and electrical testing, your equipment should run well for years to come.
