Ultrasound port enables detection of faults in electrical distribution systems and switchgear
VP12 ultrasound port
IRISS has launched the VP12 ultrasound port, which enables technicians to identify potentially hazardous and costly faults, such as arcing, tracking and corona, in electrical distribution systems and switchgear.
According to the company, the system — which can be used for either ultrasound or infrared inspection tasks — provides access to consistent-quality data regardless of the technician’s experience or the enclosure rating.
In ventilated switchgear, the port provides a standardised measurement point, but in NEMA-rated enclosures its effect is said to be even more valuable.
Technicians wearing the appropriate personal protective equipment can collect data on critical, energised equipment in accordance with the safety mandates listed within NFPA70E.
- Body measures 6.5cm in diameter and features a 1.2cm port
- Port is manufactured using non-conductive, UL94 switchgear-grade plastics and insulated to 30kV/mm
- Standard kit includes an infrared transmissive lens for optional and permanent use as an infrared window for small targets or small infrared camera lens apertures
- Alternative grill opening complies with the IP2X standard for maximum hole size in switchgear to prevent the accidental insertion of tools and fingers
- Lockable cover maintains IP65/NEMA 4 seal when closed and the overall unit is impact and flame resistant in line with IEEE standards
The telecommunications company, the TalkTalk Group, has appreciated the value of thermal imaging for many years. The technology is used to detect electrical faults that could disrupt its network operation, although historically, thermal surveys were only conducted during maintenance shutdowns.
The new IRISS CAP-ENV is unequivocally the toughest and most reliable infrared window available and suitable for thermal inspection of energised equipment in the visual, UV and all three infrared wavelengths.

As the saying goes, ‘garbage in, garbage out’. This truism is every bit as applicable in thermography as it is in computer data mining. The difference is that the inaccurate data that leads a thermographer to a false-negative conclusion could result in a multimillion-dollar catastrophic failure of a company’s electrical distribution system. In fact, the implications to personnel safety, plant assets and production downtime make the results of transmissivity errors more like toxic waste ...
The VPT Platinum series infrared window utilises IRISS’s Poly-View System technology to allow the use of any thermography camera to monitor energised electrical equipment.
