Airborne/metalclad acoustic detection
The ULD401 allows acoustic waves detection created by partial discharge/corona effect. A parabolic dish sensor is available for corona effect detection on HV & MV voltage apparatus such as transformer bushings and lightning arrestors.The contact acoustic sensor allows acoustic wave detection associated with partial discharge, on metalclad cabinet (switchgear) and dry type transformers.Phase resolved measurements can be achieved with the help of the XDP-II’s phase synchronization kit (n/a for XDP-II-LT). This technique allows a better noise discrimination as the measured signal is synched with the line phase.1 degree narrow measurement detection windowLaser pointerEnhancement viewing laser pointer glasses for outdoors applications
