Residual voltage
Residual voltage test is used to detect the presence of residual voltage in a system, after the main source of power is disconnected.

AC Dielectric Strength Test
The AC dielectric strength test is performed by setting an acceptability threshold of the maximum current.
DC Dielectric Strength Test
The DC dielectric strength test is carried out when there are very significant capacitive currents.
Electrical resistance test
Testing the electrical resistance of a winding is essential and is performed to measure the resistance of a winding.
Dielectric absorption ratio (DAR)
The dielectric absorption ratio is important in the case of insulating materials in which the absorption current decreases rapidly.
Partial Discharge analysis (PD)
Partial discharges (PD) are electrical discharges localized in the dielectric insulation, limited only to a part of the dielectric material.
Polarization index (PI)
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.
SURGE test
The SURGE test is the most reliable method to test the insulation of winding systems and can also be used to test partial discharges.
DC insulation resistance test
The DC insulation resistance test evaluates the quality of the insulators, the possible presence of humidity and pollution.
Die cast rotor test
This test has been carried out by RISATTI INSTRUMENTS since 1975, for the immediate detection of the main defects found on die-cast rotors.
