High voltage measurement

Since optical electric-field probes allow the measurement of strong electric field, both continuous wave (CW) and transient (lightning strikes and surge voltages), safely and under extreme conditions (vacuum, high pressure, oil immersion), KAPTEOS solution meets the needs of electric field measurements and diagnostic for high voltage measurement inside equipment.

 

KAPTEOS has conducted many studies and manufactured numerous systems on behalf of its clients: characterization of dV/dt on power electronics components, electric-field mapping on new or active equipment, partial discharge assessment, dielectric barrier discharge measurements and characterization of electrical discharges such as lightning (1 MV, 40 kA).
