VPDS Series
The VPDS Ultrasound Sensor is the most effective and safest way to perform ultrasound inspection on energized electrical assets from low to high voltage. Ultrasound electrical inspection has been relegated to scanning the seams and opening of electrical assets for years. Oftentimes, the inspector runs into antagonistic ultrasound from other sources, limiting the inspector from achieving the critical angle of the incident wave to analyze the best sound wave. To improve the effectiveness and safety of the ultrasound inspector, IRISS designed the first Ultrasound Sensor that is mounted in the panel with a transducer on the inside facing the gear. With its 3.5 mm headphone jack, almost every make and model of ultrasound testing device can plug in and listen to the gear safely from the outside. This allows the inspector to quickly identify the existence of potentially hazardous faults such as corona, treeing, tracking, delamination of windings and loose connections.
Arc Safety Tested
Successfully tested to the IEC 62271-200 standard for arc containment on metal enclosed switchgear assemblies to help protect workers from injury/fatality.
Durable and Rugged
Polymer based IR windows are far more able to resist the mechanical stresses applied to IR window that are fitted to electrical distribution equipment.
UL Listed
Having passed rigorous standards and testing, our inspection windows are UL Listed (E491496). This demonstrates our dedication to continued safety and security in the ever-changing world of electrical power.
Environmentally Sealed Design
The VPDS Series of products are constructed from switchgear grade Nylon plastic with an aluminum cover and stainless-steel mounting screws. Seamless custom gaskets ensure the NEMA4 / IP65 ingress protection rating is maintained.
Embedded 40KHz Airborne Ultrasonic Port
Quickly and Safely perform closed panel airborne Ultrasound inspections of electrical equipment including Switchgear, Switchboards, Panelboards, Transformers, Motor Control Centers and Process Equipment Panels. Through the VPDS’ embedded 40KHz Airborne Ultrasonic Ceramic Transducer with 3.5mm jack socket compatible with IRISS PD and TEV testing devices such as the Sonus XT & Sonus PD to detect early warning signs such as Arcing, Tracking, Corona and Partial Discharge.
Arc Containment Tested
The VPDS was successfully tested to the IEC 62271-200 standard for arc containment on metal enclosed switchgear assemblies. In addition, the VPDS has been used extensively by OEMs in UL Arc Resistant switchgear designs and have successfully passed every Arc Resistant type test to which they have been subjected.
Fast and Easy Installation
Following a few simple instructions, IRISS inspection windows can be quickly installed on switchgear and MCC panel covers, as well as transformers and other electrical equipment. Each window comes with an installation guide, as well as links to installation videos.
