Materials characterization

Characterization of insulating materials for electrical systems

Short-time properties

• Electric strength
• Space charge build up and dynamic of decay
• Electrical conductivity
• Broadband Dielectric Spectroscopy (polarization/depolarization currents, permittivity)

Medium-long time properties

• Electrical / thermal /mechanical endurance (electrical life tests)
• Partial discharge endurance
• Aging investigation and life modeling of polymeric insulating materials and systems

Cable interface assessment

Model samples efficiently simulating cable joints

• PD activities
• Space charge build up and dynamic of decay
• Conduction and leakage current
