World’s first ultrasound port from IRISS
03 September 2012
Arcing, tracking and corona are sure signs of potential failure in electrical distribution systems and switchgear. An ultrasound gun can detect these early warnings easily but only if the sound quality is good enough to provide a viable reading. Furthermore, the data collection must be repeatable and reproducible for any condition-based monitoring programme to reveal a trend and grade severity.
IRISS claims its new VP12 is the world’s first ultrasound port that allows access to consistent quality data, regardless of technician experience or enclosure rating. It enables potentially hazardous and costly faults to be identified efficiently during routine inspections.
With a body diameter of 6.5cm, the IRISS VP12 provides a 1.2cm port. In ventilated switchgear, the port provides a standardised measurement point but in NEMA-rated enclosures its effect is even more valuable. This new IRISS product supplies the only access where technicians, wearing appropriate PPE, can safely collect data on critical, energised equipment in accordance with safety mandates found within NFPA70E.
Manufactured using non-conductive, UL94 switchgear-grade plastics and insulated to 30kV/mm, the IRISS VP12 can be used either for ultrasound or for IR inspection. The standard kit includes an IR transmissive lens for optional and permanent use as an IR window for small targets or small IR camera lens apertures.
The alternative grill opening complies with IP2X standard for maximum hole size in switchgear to prevent accidental insertion of tools and technicians’ fingers. A lockable cover maintains IP65/NEMA 4 seal when closed and the overall unit is impact and flame resistant in line with IEEE standards.
IRISS says the VP12 has been approved by all the leading manufacturers of ultrasonic instruments.
