| Use advice for data set | The life cycle assessment of the TPU 53.23, an EEPS (Electronic and Electrical Products and Systems), is a “cradle-to-grave” analysis. The figure below shows the product life cycle stages and the information considered in the LCA. |
| Technical purpose of product or process | The product declared in this Environmental Product Declaration is the indoor current transformer TPU 53.23 1250//5/5 A, including related accessories and packaging. The instrument current transformer TPU 53.23 is a measuring and protecting device which is standardly used in medium voltage indoor switchgears for transforming high primary current into low current on secondary side which can be safely used controlling and monitoring in relay devices. Most common type of switchgear is UniGear ZS1. The constituent materials of TPU 53.23 1250//5/5 A are presented below.

| General comment on data set | Both primary and secondary data are used. The main sources for primary data are the bill of materials and technical drawings, while site specific foreground data are provided by ABB. Furthermore, information and data obtained from other LCA studies are also used. For all processes for which primary data are not available, generic data originating from the ecoinvent v3.9.1 database, “allocation, cut-off by classification”, are used. The LCA software used for the calculations is SimaPro 9.5. The utility consumption and waste generation by ABB, in the core manufacturing stage, is allocated to the production of one reference product according to applicable rules. For the end-of-life allocation, the “Polluter Pays” principle is adopted according to what is defined in the CEN/TR 16970 standard. However, the potential benefits and avoided loads from recovery and recycling processes are not considered because it is not required by the PCR. The materials that were excluded are glue, and adhesive, as their mass represents less than 2% of that of the whole product, as stated in the paragraph of cut-off criteria of EPDItaly015: “Materials making up the transformer itself whose total mass does not exceed 2% of the total weight of the device”. The same applies for tape and labels used in packaging, which are even a smaller fraction of the total mass. Sandblasting of capacitors and phosphating were also excluded due to the model complexity and unavailability of reference data. |
