The testing section carries out the series onests below on all transformers :Ratio Test - Resistance Measurement - Polarity and Phase Relation Test - No-Load Loss Test 1ZCL000001EG-EN User's Manual3.2.1 Storage of transformers with sealed tank Transformers completely assembled Check the internal pressure of the transformer:If the pressure gauge indicates a vacuum or pressure lower than 0.1 atm. (2 Psi), pressurize with 2 or 3 pounds of Nitrogen and check at 1ZVN460100-B Installation manual - ABB Group5.2. Mounting the COPS Oil Preservation System If the transformer is equipped with a constant oil pressure (COPS) oil preservation system, mount the support structure for the COPS tank, mount the tank and install the valves on the main tank and the COPS tank. The valve to the COPS piping on the transformer cover should remain closed.
