SERVICES, AND AFTER SALES SERVICE
OTTAVI srl is also synonymous with after-sales service and maintenance, ordinary and extraordinary, as well as timely and accurate service activities, namely:
- Revamping of transformers;
- Rental and loan of use of transformers new or used;
- Internal laboratory capable of performing oil analysis: control of the values on the isolation dielectric, on the content of PCBs, PCTs, acidity;
- Operations of control and verification of the transformers also on places where they are operating;
- Rehearsal room inside can perform all tests and tests and final production.

RENTAL AND LOANS
Rents and loans of use of new and used transformers
TESTS
• Control of transformers with appropriate equipment, even on site
• Oil Analysis: dielectric insulation, the PCB, PCT, acidity, etc.
• Rehearsal room inside can perform all tests and inspections of production and final according to CEI EN 60076-11:
Oil transformer:
- Measurement of the resistance of the windings
- Measurement of the transformation ratio and verification of vector group
- Measurement of short circuit and losses borne
- Extent of the losses and the load current
- Insulation test voltage induced
- Insulation test with applied voltage
Resin transformers:
- Measurement of the resistance of the windings
- Measurement of the transformation ratio and verification of vector group
- Measurement of short circuit and losses borne
- Extent of the losses and the load current
- Insulation test voltage induced
- Insulation test with applied voltage
- Test pulse and frequency
OTTAVI srl advancing, always with a view of the after-sales service, and in the specific context of significant supply or specific needs of the Customer, training courses at their own production units, in order to support the competence and professionalism in the service. So a real tool for the Client itself, by means of which you will always keep particularly efficient and updated the performances of the machines used.
The company also has a fleet of transformers, both oil and resin, declined in the more usual power and voltage, for use in all emergency situations that require the immediate restoration supply suspended in the various fault conditions.
