Railway stators

Machines for railway stators testing

For testing railway stators, Risatti produces machines suitable for large stators, with low inductance values.

Risatti makes customized solutions, according to the customer’s needs. The tests on railway stators can be performed individually or in an automatic sequence. Suitable safety measures can be designed together with the Customer (e.g. protection doors, optical barriers, remote controls).

During these years, Risatti has gained a high level of experience and specialization in the sector, due to the collaboration with important national and international companies. In addition to testing the stator, the Risatti range is also completed with solutions for testing the rotor.

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.
