A standard and systematic approach to data collection is essential to establishing a repeatable and reproducible condition based monitoring program. VP-12-US standardizes the location and method for accessing consistent and quality acoustic data regardless of the ultrasound technician’s experience or enclosure rating. Easily identify potentially hazardous faults such as arcing, tracking and corona in electrical distribution systems and switchgear through the VP-12-US. NEMA rated enclosures require only access through the port where technicians can safely collect data on energized equipment in accordance with NFPA 70E safety mandates. The grill allows ultrasound but prevents objects being pushed into the panel.
