There is no specific parameter for selecting the transformer type to buy. It depends mainly on the project devised according to customer requirements; it also depends on the location where it will be installed e.g. indoor or outdoor, the Country of installation as well as the type of plant that it will feed e.g. solar power plant, furnace supply etc.
We ensure an adequate flexibility according to customers requirements.
Before being put on the market our transformers are tested in compliance with CEI EN 60076-11 standards. FAT (factory acceptance tests) are included in the price and are performed by expert technicians directly at our plant. It is possible for the customer to attend the testing procedures.
TYPE TESTS AND SPECIAL TESTS are available upon request at an extra cost and they are performed at external facilities managed by internationally accredited bodies such as CESI – Milan
Special tests include:
Once the transformers are tested they are bolted and strapped on wooden platforms, tailored upon their size and they are finally packaged with shrink firm in order to create a protection against humidity and atmospheric agents.
We do not take care of the installation at site.
The production process implemented by Elettromeccanica Piossasco is in compliance with a Quality Procedure developed according to ISO 9001:2008, accredited and verified by DNV (DET NORSKE VERITAS) accreditation body.
Up to June 2015 Dry Type cast resin transformers were regulated by IEC 50541-1:2011 standards and Oil Immersed transformers by IEC 50464-1:2007 standards
FROM THE 1st OF JULY 2015 …
The preceding rules were replaced by the new European standard EN 50588-1 according to EU Regulation 548/2014 issued by the European Commission with the aim of achieving greater energy efficiency and a general environmental compatibility of electrical appliances, with a reduction of CO2 emissions. The directive will be implemented in two steps: the first from the 1st if July 2015 and the second, which provides stricter standards, is scheduled for 2021.
Let’s get to know it…
EN 50588-1 introduces technical innovations for both oil and cast resin transformers from 25 kVA to 40 MVA rated power. The aims are, in fact:
It is also introduced the concept of PEI (Peak Efficiency Index) for transformers featuring a rated power greater of 3150 kVA.
