Name
250KVA-10.5/400V ZNyn5 Auxillary Earthing Transformer
Technical purpose of product or process 250KVA-10.5/400V ZNyn5 Auxillary Earthing Transformer, ZENA0019958 manufactured by Kyte Powertech Limited, Cavan, Ireland. The product is unambiguously identified as a 250 kVA oil-immersed earthing transformer designed and manufactured in accordance with applicable IEC standards for power transformers. Technical and Functional Characteristics The transformer is as an auxiliary earthing transformer and operates under the following technical specifications: Rated power: 250 kVA Frequency: 50 Hz Primary voltage (HV): 10.5 kV Secondary voltage (LV): 400 V Vector group: ZNyn5 Cooling method: ONAN (Oil Natural Air Natural) Short-circuit impedance (uk): 4% with a zero sequence impedence of 18.19 ohm/ph Maximum operating voltage (Um): 12 kV Power frequency withstand voltage (AC): 28 kV Lightning impulse withstand voltage (LI): 75 kV Environmental class: A The transformer is hermetically sealed and filled with mineral insulating oil, which provides both electrical insulation and thermal management. The core is constructed from grain-oriented silicon steel to minimize magnetic losses. Windings are manufactured from aluminium conductors with oil-impregnated paper insulation. Relevant Technical Data and Reference Service Life (RSL) The declared Reference Service Life (RSL) is 30 years, assuming normal operating conditions and appropriate maintenance within electrical distribution networks. Intended Application The transformer is intended for use in electrical energy distribution networks, typically installed in substations or distribution points within industrial, commercial, and residential power systems. Applicable Standards and Testing The product is designed and tested in accordance with applicable IEC standards for power transformers, including but not limited to: IEC 60076 series (Power Transformers) Routine, type, and special tests are performed according to the relevant IEC standards before dispatch.

1This impact category deals mainly with the eventual impact of low dose ionizing radiation on human health of the nuclear fuel cycle. It does not consider effects due to possible nuclear accidents, occupational exposure nor due to radioactive waste disposal in underground facilities. Potential ionizing radiation from the soil, from radon and from some construction materials is also not measured by this indicator.
2The results of this environmental impact indicator shall be used with care as the uncertainties on these results are high or as there is limited experiences with the indicator.
