Substation maintenance

Question and Answer:

1. Do you all need the full testing done on the liquid filled transformers? Do you all want to Doble test the transformer?

Answer: The tests that are to be performed on the transformers are listed under 2.0 GENERAL REQUIREMENTS titled Transformers: Liquid-filled: All voltages Visual and Mechanical Inspection, all the items that are listed below that title will be performed if it applies to a particular transformer. We expect recommendations after all the inspections are made in this statement of work.
