ACTIVITIES - MEASUREMENTS, TESTS AND TESTS

TECHNICAL EXCELLENCE FOR OUR PARTNERS

Pittarello Imel with high work experience in the field of overhaul, maintenance, technical assistance / consultancy and testing (directly on site), of HV industrial power transformers. and distribution in M.T. and any other electrical equipment, normally present in an electrical system (such as for example: Circuit Breakers, Disconnectors, CTs, VTs, TVCs and Protective SPDs).
The immense passion and the enormous dedication for these very important activities, combined with the trust given to him over time by his customers, appear to have been the ingredients, which have allowed all the personnel interested in these activities to grow professionally and consolidate satisfactory knowledge. and experiences.
Knowledge and experience that after so many years now allow not only to propose, but also to put into practice innovative solutions, capable of responding day after day to the needs of a constantly evolving market, both technological and structural.
With the use of its own staff, its own vehicles and cutting-edge work equipment, Pittarello Imel can provide appropriate technical advice for any type of failure occurred to any electrical equipment in HV. and M.T.
Thanks to its highly specialized technical staff in measurements and tests and its innovative and versatile instrumentation, it is able to test any transformer, switch and disconnector both of H.T that of M.T., being able to carry out the following electrical tests on these:

List of the main tests that can be carried out on H.T transformers and M.T.

  • Resistance
  • Relationship and polarity
  • Excitation current
  • Short circuit impedance
  • FRSL (Freq. Response of Stray Losses)
  • Capacity
  • Tang.δ
  • Dielectric frequency response
  • Magnetic balance
  • Dynamic resistance
  • Contact times (DRM)
  • Insulation resistance
  • Moisture content
  • Core insulation
  • Contact resistance
  • Demagnetization of the magnetic core

List of the main tests that can be performed on HV and MV circuit-breakers and disconnectors

  • Maneuver times and non-contemporaneity
  • Absorption of electric control coils
  • Speed, stroke and over stroke of the poles
  • Absorption of electric motors
  • Operating pressures and blocking thresholds
  • Contact ohmic resistance, static

Pittarello Imel, directly at the customer plant (Station / Primary substation / Secondary substation / Power plant, Industrial site etc …), thanks to its highly specialized technical staff and the special equipment / mobile equipment supplied, is able to :

  • Carry out any predictive or systematic revision / maintenance intervention, as well as any type of treatment (filtering and degassing) of the insulating oil, (both these, mineral oil, silicone or vegetable ester), on transformers or autotransformers in HV or MV of any power.
  • Eliminate any oil leaks: a) From the box; b) From the unit heaters, c) From the radiators; d) From pipes or cooling waves; e) From the lid gasket; f) From insulators; g) From the various gate valves present in it; h) From the container of the circuit breaker of the c.s.c .; i) From the operations of the commutator, of reg. and / or voltage change; l) etc….
  • Replace: a) all rubber gaskets found to be old; b) any damaged insulators; c) various accessories or anything else that is found to be faulty or damaged upon inspection.
  • Iinspect the active part of the transformer off-box to establish both its state of life and the maintenance interventions that are necessary on it. To carry out thorough cleaning with new, hot, treated insulating oil, including the total elimination of any decomposition substances present in it and sometimes deposited anywhere.
  • Carry out an accurate external cleaning of the case, eliminating all the rust present in it and then proceed with its complete painting;

La Pittarello Imel, su qualsiasi tipologia di trasformatore elettrico, può inoltre effettuare:

1) Qualsiasi tipologia di prelievo d’olio isolante per l’effettuazione delle consuete periodiche analisi chimico-fisiche;
2) Qualsiasi tipologia di prelievo d’olio e gas di Buchholz, per le indispensabili analisi gascromatografiche che necessita assolutamente effettuare a seguito di un qualsiasi guasto elettrico interno, occorso al trasformatore sotto esame.
3) Qualsiasi intervento di revisione/manutenzione, predittiva, sistematica e/o straordinaria, su trasformatori ed autotrasformatori in resina di ogni potenza, compreso la accurata pulizia interna della cabina o del relativo box di contenimento.

Pittarello Imel can intervene in the manipulation of the SF6 gas (hexafluorurodizulf) contained in the electrical equipment having suitable equipment and licensed personnel according to the EXECUTION REGULATION (EU) 2015/2066 OF THE COMMISSION of 17 November 2015 which establishes, in accordance with the regulation (EU) n. 517/2014 of the European Parliament and of the Council, the minimum requirements and conditions for the mutual recognition of the certification of natural persons involved in the installation, assistance, maintenance, repair or deactivation of electrical switches containing fluorinated greenhouse gases or for the recovery of fluorinated greenhouse gases from fixed electrical switches.

  • The above allows us to:Analyze the quality of SF6 gas by measuring humidity, purity and decomposition products;
  • Treat / replace deteriorated SF6 gas on site with special wheeled equipment;
  • Top up with missing SF6 gas;
  • Leak detection in small concentrations of SF6 gas (ideal for detecting the location and size of leaks);
  • Environmental management of SF6 gas destined for disposal;
  • Online monitoring of SF6 gas through high-precision detectors of density, temperature, pressure and humidity of SF6 gas inside and outside of electrical equipment. The instruments feature high-precision sensor technology that ensures excellent long-term stability and important features for protection from electromagnetic interference (EMC).

Pittarello Imel has the most important sector certifications that allow it to operate in each area and in strategic markets, with the necessary skills.
She has always and with absolute continuity invested in training and professional qualification processes, as she is deeply convinced that this is the only way to be able to interface with increasingly demanding customers.

Pittarello Imel communicates wide availability:

  • To intervene promptly, (upon explicit request), at the customer plant for the examination of any faults that have occurred or for the resolution of any problems relating to transformers and electrical equipment of both HV and MV
  • To carry out, (upon explicit request), at the customer plant, all the inspections that are necessary, for the preparation of the estimate of the work to be performed.
