The ANSI/NETA MTS Standard for Maintenance Testing Specifications for Electrical Power Equipment and Systems, 2015 edition, was approved as an American National Standard on December 3, 2014 and supersedes the ANSI/NETA MTS-2011. NETA recommends always referencing the most current edition of the ANSI/NETA standards whenever possible to assure that bid documents, specifications, and reports are as accurate and complete as possible.

The ANSI/NETA MTS Standard for Maintenance Testing Specifications for Electrical Power Equipment and Systems is a document that is used worldwide by individuals seeking to assure that the electrical power equipment and systems in their care operate reliably and safely in conformance with industry and manufacturer standards and tolerances.

Maintenance tests are those tests that allow the determination of whether or not the electrical equipment is suitable for safe and continued service.

When dealing with service-aged equipment, many criteria are used in determining what equipment is to be tested, at what intervals, and to what extent. Ambient conditions, availability of down time, and maintenance budgets are but a few of the considerations that go into the planning of a maintenance schedule. The owner must make many decisions each time maintenance is considered. It is the intent of the ANSI/NETA Standard for Maintenance Testing Specifications for Electrical Power Distribution Equipment and Systems to list a majority of the field tests available for assessing the suitability for continued service and reliability of the power distribution system.
