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.
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.
Tan Delta
The Tan Delta Test allows determining the relationship between the currents that naturally circulate and those caused by losses.
Rotation Test
The rotation test is specific to electric motors, including fully assembled motors and stator.
PE/Ground AC
The Protective Earth – PE or ground earth test measures the earth ground rod’s resistance.
