Electrical Inspection

Used in combination with ultrasonic testing device SONAPHONE, the parabolic dish SONOSPOT detects damages that are difficult to reach or further away e.g on transmission and distribution lines. The high sensitivity and the precise directionality of the sensor allows detection of electrical partial discharges and damage at electrical insulations on e.g. medium-voltage equipment or switchgears. PD activity increases over time and can lead to progressive and irreversible damage in insulation systems.

Regular inspection of equipment is essential for preventative maintenance. The SONAPHONE can be used to detect and distinguish stages of corona, tracking and arcing, for high, medium and low voltage applications, to inspect open or closed electrical systems, to inspect switching cabinets, control boxes, relays, transformers, insulators, etc.
