Electric conductivity

• Setral house test
• Test setup: measuring cell + insulation tester or + high-impedance tester (for insulating greases)
• 2 measuring cells
• Oils: cylindrical cell
• Greases: plate cell
• Output: electrical resistance and cell contacts (for example by reference substances like H₂O)
• Electric conductivity Sigma [S/cm] = electric conductance constant of the measuring cell = (1 / R) * K [ S = (1 / Ohm) * cm^-1]
