CONSTRUCTION FEATURES Transformers are manufactured using a copper or aluminium winding (according to the rated power and the economic optimisation of the project or the Customer’s request) and a magnetic core made of low-thickness laminations to reduce the losses The isolating material used for the main insulation towards the core and for the inner insulation of windings is selected according to the required insulation class. The solidly-built assembly, locked by plates and rods, is impregnated with environment-friendly polyester resin. The impregnation and oven polymerisation processes consolidate...

STANDARDS OF REFERENCE The regulatory references follow an international chain that defines harmonised standards and is made up of IEC (International Electrotechnical Commission), CENELEC (European Committee for Electrotechnical Standardization) and CEI (Italian Electrotechnical Committee). The standard technical reference provision for transformers manufactured by Ortea Next is the following: CEI EN IEC 60076 power transformers (divided into several parts). When applicable, for isolating transformers reference is also made to CEI EN IEC 61558 safety of transformers, power supply units and similar...

Thermal class The thermal class indicates the maximum allowable temperature (hot spot) for the winding of a transformer operating at an ambient temperature of 40°C and is classified into various levels by defining temperature ratings. The following table summarises the different thermal classes available. All transformers emit noise due to the alternating flow within the magnetic core. If the transformer is installed near populated areas, the noise level may become a factor to be evaluated and considered. For all transformers above 50kVA, the noise level is checked after 12 hours of no-load connection...

The polyester resin has a much higher dielectric strength and adhesion properties than any paint or other encapsulations, including oil-modified epoxies. Polyester resin have the following characteristics: • Low moisture absorption (non-hydroscopic). • High dielectric strength. • High bond strength. • Excellent mechanical properties. • High temperature stability. • Excellent thermal shock properties. • Long life at maximum transformer temperatures. For a longer life, it is essential that integrity of dielectric properties of the transformers' material insulation is maintained. Transformers are...

Accessories In order to fully comply with the Customer's requirements and the applicable standards, the manufacturing process includes intermediate and electrical tests executed on all the items produced • Size, rated data and data plate check. • Terminal identification check. • Vector unit test. • Dielectric properties test (dielectric strength at 3kV and insulation resistance). • Transformation ratio test. • No-load test (checking: secondary voltage, current absorbed without load, magnetic core losses). • Load test (checking: percentage short-circuit voltage, winding losses). • Electro-static...

A three-phase transformer is designed to transform an input voltage into the required single-phase or three-phase output voltage To calculate the rated power (kVA) when the voltage and current are known: To select the correct type of transformer you need to determine: The total load is often a combination of individual singlephase and three-phase loads (e.g. lights, heaters, motors). You need to know the characteristics of the individual loads: active power, power factor, unbalance, etc. The total load must be evaluated taking into account the appropriate usage and contemporaneity factors. The...
