Abstract

This article is oriented to the structuring a technical guide for acceptance and maintenance tests for two equipment of the medium voltage electrical system, these are combined measurement transformers and Pad-mounted Load-Interrupter switchgear, also, the recommendation of the laboratory devices necessary to make said tests within the Empresa Eléctrica Quito (EEQ) laboratory and in the field. The necessary information on the equipment was obtained through visits to the EEQ transformer laboratory and the companies that manufacture them. The investigation of the international regulations that are applied to each of the devices, and the characteristics of the instruments for the development of the tests, was made through the Servicio Ecuatoriano de Normalización (INEN) and on the internet; Then the tests were classified into two categories: those that can be performed under current laboratory conditions and those that could be performed in the future; Finally, the test manual was made, in each test contains: its objective, the standard that is applied, the necessary equipment, the procedure to be followed and the acceptance criteria.
