TESTING:
The SURGE test is the most reliable method to test the insulation of winding systems and can also be used to test partial discharges.
The AC dielectric strength test is performed by setting an acceptability threshold of the maximum current.
The DC dielectric strength test is carried out when there are very significant capacitive currents.
The DC insulation resistance test evaluates the quality of the insulators, the possible presence of humidity and pollution.
Testing the electrical resistance of a winding is essential and is performed to measure the resistance of a winding.
1.2/50 Normalized Pulse Test simulates rapid and high-value impulses in an electric machine.
The polarization index represents one of the most significant parameters to monitor the health of an engine, with reference to the condition of its insulators.
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.
The Tan Delta Test allows determining the relationship between the currents that naturally circulate and those caused by losses.
