Multifunction testers for repairers

Risatti offers both machines for carrying out specific tests and multifunction testers, keeping in consideration the specific needs of users of all levels and to satisfy the various Italian, European and international standards.

The main objectives for this application:

  • easily identify the fault
  • show the final customer, with objective values, what type of failure occurred to the DUT
  • what kind of repair to be made
  • final testing

This last step is used to validate the intervention carried out, or to certify the repair of an electrical component.

In conclusion, carrying out tests with precise and reliable tools (such as multifunction testers), allows to obtain quality tests with objective criteria during the repair. The focus is on single pieces. Typical test objects can be summarized in stators, coils, alternators, rotors and transformers.

The versions and numerous options enable

  • easy customization of all the equipment
  • tests on electrical machines of any power and size.

The solutions are compact and offer certified test reports.

The Risatti line offers single-test machines and multifunction testers, for tests on small and large stators, single and three-phase motor stators, continuous stators, coils, alternators, small and medium-sized wound and die-cast rotors and low and medium voltage transformers both connected and disconnected internally.

Shortly, the range of machines proposed by Risatti is characterized by single-test testers, for specific tests, and by multifunction testers, which group numerous tests in a single practical tool. Furthermore, the machines offered are also adaptable to the needs of laboratory tests.

The tests

The equipment, exclusively designed and manufactured by us, embraces the entire electromechanical and electrotechnical sector and the sectors related to preventive maintenance, repairs and rewinding.
Residual voltage test is used to detect the presence of residual voltage in a system, after the main source of power is disconnected.
The AC dielectric strength test is performed by setting an acceptability threshold of the maximum current.
Testing the electrical resistance of a winding is essential and is performed to measure the resistance of a winding.
The dielectric absorption ratio is important in the case of insulating materials in which the absorption current decreases rapidly.
Partial discharges (PD) are electrical discharges localized in the dielectric insulation, limited only to a part of the dielectric material.
