resin Transformers With the application in July 2015 of the European Commission Regulation for ecodesign, efficiency standards of transformers will be more strenght The Green T.HE Transformers comply with the EN 50588-1 Standard. They are designed and manufactured according to the Regulation 548/2014 of European Commission and the new Ecodesign guidelines 2009/125/CE. Legrand Green T.HE Transformers, designed and manufactured in accordance with new Regulation, ensure a consistent reduction in energy consumption, resulting in economic savings and the decrease of CO2 emissions released into the...

CLASSIFICATION The classification of a cast resin transformer depends on the value of the no-load losses (P0), as well as the load losses (Pk). More precisely P0 losses are independent from the load and remain constant for the whole period the transformer is connected to the electric power network. On the other hand, Pk losses only occur when the transformer is connected to a load and they are proportional to the square of the load. ECODESIGN REQUIREMENTS

TRANSFORMERS Low, partial discharges, HIGH Quality According to the product standard related to design of resin transformers (CEI EN 60076-11, i.e. IEC 60076-11), all the windings with a voltage ≥ 3.6kV should be subjected to the measurement of the partial discharges and the value measured should not exceed 10 picocoulombs (pC). Partial discharges are a microscopic phenomena occurring inside insulating resin cavities and can speed up ageing. For this reason, it is important that the values of such currents are limited. A low value of partial discharges gives an indication of the positive factors,...

Reliability guaranteed With Green T.HE series, Legrand provides customers a top-quality product which guarantees long-term excellent performance and reliability. When the Green T.HE transformers are subjected to partial discharges (according to CEI 60076-1 1, i.e. IEC 60076-1 1), values under 5 pC have been always been achieved (which exceeds the requirement of the standard which establishes the maximum value at 10 pC). Thanks to the excellent quality of products, Legrand has extended its GUARANTEE to 8 YEARS for all its transformers with standard features (*). Green T.HE series is certified...

Ventilation bars The ventilation busbars temporarily increase the rated power (under normal service conditions). According to standard IEC 60076-1, a transformer is called AN even if it is equipped with discontinuous ventilation. If a transformer with AF continuous service is requested, it is not possible to refer to the codes included in this catalogue, but the transformer will be designed according to the customer's needs.
