It has long been known that "Dependability can be engineered and built into equipment, but effective maintenance is required to keep it dependable". Where do we get the guidelines to ensure the maintenance programs we design are effective?
Electrical equipment deterioration is normal, but equipment failure is not inevitable. As soon as new equipment is installed, a process of normal deterioration begins, however, an effective maintenance program identifies and recognizes these factors and provides measures for coping with them and can provide significant returns on Energy savings, as a correctly maintained plant runs more efficiently and uses less energy.
When it comes to an electrical maintenance program, there is no better place to start than NFPA 70B. This document outlines from start to finish the main parameters for a successful Electrical Maintenance program.
In Chapter 8 of "10 Things You Need to Know About Infrared Windows" by IRISS, you will find more information on what NFPA 70B suggests as frequency of inspections and how to carry out these inspections, safely and efficiently.
