    The transformers are static electric machines, because at simple view, they are not generated any movement. But internally electric efforts exist, mechanical efforts, changes of temperature that generate movement that cannot perceive at simple view. Therefore, the distribution transformers and in general, all the classes of transformers need to be proven with different teams for each one of the tests that is required, before putting into operation. In the Chapter one is described the operation of the teams to use, class and parts of the distribution transformers and the tests to be carried out with the respective norms. The Chapter two makes to the interpretation of results of the surveys carried out to the Companies. In the Chapter three is detailed in more specific way the tests to carry out for the distribution of transformers. In the relating the electric tests, it is described the following mensuration: test of relation transformation, test resistance of those reeled, isolation resistance test, rigidity dielectric test and short circuit test. In the annexes are detailed the planes of the area of the laboratory, circuits of illumination and forces, as the previous leaves to the mensuration and for finishing procedure of each one of the tests.
