Experience teaches us that experimental activities are veryimportant and necessary every time the electric phenomenaare complex and the choices related to the project seem tobe very difficult. It is convenient for the electric equipmentto be tested in different conditions according to theinternational standards, to check not only the electric,dielectric, thermal and mechanic performance but also theperformance related to safety and life cycle. The complianceto IEC/EU Standards is an essential requirement and we areable to guarantee it. A higher reliability and a longer lifetime of products can open the way to the success. Siemens,thanks to the SVEPPI laboratory and related test capabilitiesallows you to carry out several kinds of electrical andmechanical tests. The tests are carried out according to themain technical standards. Built in the early 50ies it is locatedclosed to Terna Substation of Scorzè and connected witha dedicated 220 KV bay.
