FAQ

DOMANDE FREQUENTI

Is it better to buy a cast resin or oil insulated transformer?

There is no specific parameter for choosing the type of transformer to buy; it mainly depends on the project that will be made based on the customer’s requests. It also depends on where it will be installed (for example indoor or outdoor), on the country of final destination as well as on the type of plant it will power (for example photovoltaic, power supply ovens, etc.)

Delivery time?

Adequate flexibility is provided based on the customer’s request.

Tests on Elettromeccanica Piossasco Srl transformers

Before being placed on the market, our transformers are all subjected to testing according to the procedures set out in the CEI EN 60076-11 standard..

Routine tests are included in the price and are carried out in our workshops by expert personnel. It is possible to witness the tests.

At the customer’s request (and at an additional cost) type tests can be carried out in laboratories managed by recognized external bodies, such as the CESI laboratory (Milan), and also special tests including:

  1. Short circuit withstand test
  2. Lightning impulse withstand test
  3. Temperature Rise test
  4. Noise Level test
  5. Once the testing is complete, the transformers are bolted and strapped onto wooden pallets (specially made according to the different sizes of transformers of our construction) and finally packed with thermo-film, in order to create protection against humidity and atmospheric agents

Transport and Installation ?

As for the transport, we will evaluate together the most suitable solution to meet your needs.

The installation, on the other hand, is not our responsibility.

Do you have certifications?

Elettromeccanica Piossasco’s production is based on the application, in its process, of a quality assurance system, developed in accordance with the ISO 9001: 2008 standards, accredited and verified by the certification body DNV (DET NORSKE VERITAS).

In September 2021, following tests carried out on our transformers, at KEMA (Cesi Group) laboratories, we obtained the E3-C2-F1 certification for resin transformers.

Regulations in force?

Until June 2014 the resin transformers were regulated by the CEI EN 50541-1: 2011-04 Standard and the oil transformers by the CEI EN 50464-12007-08 Standard.

From 1st July 2015 both aforementioned standards have been replaced by the new European standard EN 50588-1, pursuant to EU regulation 548/2014 issued by the European Commission, which aims to achieve greater energy efficiency and general environmental compatibility of the electrical appliances with consequent reduction of CO2 emissions.
The directive was applied in two phases: the first phase was introduced starting from 1st July 2015 and the second, which provides even more stringent and performing standards, was introduced from 1st July 2021.

Let’s get to know this new standard better…

The EN 50588-1 standard introduced technical changes both for oil transformers and resin transformers (from 25 kVA to 40 MVA) including:

  1. The reduction of induction for no-load losses
  2. The reduction of the density due to load losses
  3. The concept of PEI (Peak Efficiency Index) was also introduced for transformers with power >3150 kVA

ENERGY FOR THE ENVIRONMENT

Photovoltaic system

Due to the process of environmental degradation that our planet has undergone, environmental protection has become one of the main problems at the global level.

We are active for the resolution of this problem, in fact we recycle all the waste from production, the disposal is checked and we carry out separate collection.

In 2010 it was also built, adjacent to the headquarters of Elettromeccanica Piossasco, a photovoltaic system that allows us t
