Our Quality,
your Guarantee.
The Quality Policy has always characterised the strategy of Mitoli transformers, whose general objectives are:
- customer satisfaction
- continuous and planned improvement of all processes, based on prevention
- improving the efficiency and effectiveness of the business system.
With this in mind, the Mitoli transformer quality system includes the following steps:
A
Input checks
They are carried out, on all incoming parts, having as their object:
- the integrity of the packaging and the products contained therein;
- the presence and completeness of an identification tag for the goods sent, placed on the containers by the supplier;
- the correspondence between what is stated on this tag, what is stated on the accompanying document and the relevant Orders.
They are carried out on all batches supplied and before they are allocated to stock, in two ways:
- a dimensional check, carried out on a statistical sample, always referring to the "critical" quotas indicated above and reported by RGQ on an "Inspection Record Sheet" (this is done in the absence of the CQC).If both the checks and the controls carried out have a positive outcome, it is the latter's task to place the controlled goods in the warehouse, referring to the map and send the Transport Document (Ddt) to Logistics for loading the goods in the IT System.

Acceptance Checks
C
Production check
They are carried out during the preparation and production phases of the product and concern the individual parts and semi-finished products obtained in the various intermediate phases (winding, sheet metal assembly, bracketing, etc.). It is the task of the self-monitoring employee to carry out checks, generally visual, on all the semi-finished products. At this time, the production report, obtained by entering certain variable data (batch no., employee serial no., phase no., etc.). into a local computer system, will only be made by the employee once all the controls foreseen in the cycle have been passed. Subsequent viewing of the "Production Statistics" printout will make it possible to identify, for each production phase and batch, the name of the employee who carried out the checks and who took responsibility for "releasing" the product to the next phase, in the event of a positive outcome of the checks carried out.
The final inspection of MITOLI transformers is aimed at verifying, from the end customer's point of view, whether the electrical characteristics measured are compatible with those expected, and coincides with the functional test, carried out on the transformers prior to their impregnation, shipment or storage. Mitoli transformers have two ways of carrying out the final inspection of transformers. The choice is decided by the Design Manager and formalised on the Technical Data Sheet, during the design and engineering phase of the transformers.

Final checks
E
Routine testing
- Resistances at room temperature
- Insulation
- Rigidity
- Increased frequency
- Watt losses of the plate
- No-load measurements on voltages.
The positive outcome of the functional checks carried out, and therefore their release to the subsequent stages, is formalised and made evident by the printing of the plate indicating the date of the test, progressive number and batch (the test data are regularly recorded on the computer system) and is automatically carried out by the equipment on all transformers; its placement on the transformer by the final control officer will allow its "release" and possible subsequent traceability.In the event of a negative outcome, the transformer will be relegated to a special area and the procedures for dealing with the identified non-conformity will be established.
In addition to routine testing, it is carried out by the Design Manager on a prototype when it coincides with the Validation (or Internal Approval) of a new project or when explicitly requested by the customer.
The positive outcome of the functional check carried out, and therefore its release to the subsequent phases, is formalised and made evident by the completion of the test sheet, by the person in charge of Design, in which the positive judgement of the tests carried out is highlighted.
In the event of a negative outcome, the transformer will be relegated to a special area and arrangements will be made for dealing with the identified nonconformity.
