In most cases, the research for a maintenance audit can typically be completed in just a short amount of time. This means that it doesn’t require a large team from the auditing organization, and that it shouldn’t demand a large commitment of time and resources from the utility.

Although the firm performing the audit doesn’t need to devote a large team to the initial review, it does need an extensive background in the field of transformer and electrical equipment
maintenance and repair. This firm should possess the following qualifications:

  • Experience with the full transformer and electrical equipment lifecycle, from initial acquisition through end-of-life decommissioning
  • An in-depth understanding of the supply chain for transformers, electrical equipment, and replacement parts
  • A working knowledge of the strengths and weaknesses of the full range of transformers and other equipment in use today
  • A track record of applying national best practices for transformer maintenance, testing, and inventory management
  • The capabilities needed to deliver on every aspect of the audit’s recommendations

The value of a maintenance audit is largely dependent on the experience and knowledge of the firm performing it. In essence, the audit is evaluating the current programs and equipment of the utility, based on what others are doing in the industry and what is possible to accomplish with the best available technology and most effective procedures.

This means that companies offering a diverse range of services to a large pool of customers will have the best insight into today’s challenges and the most effective approaches for addressing them.
