  • Distribution Switchgear
    Distribution Switchgear. Covering general principles of the Switchgear function, this invaluable reference discusses topics such as interruption techniques, fault level calculations, switching transients and electrical insulation.
  • Is Electrical Switchgear Safe?
    In today's infrared community, we talk a great deal about "What is safe?" when it comes to electrical equipment and internal-arc flash. Thermographers generally assume that with the covers and doors closed, the switchgear is in a totally safe work condition. This paper explores the differences
  • Important Condition Monitoring of Switchgear
    Process industries in the core sector, such as refineries, depend upon reliable electrical power supplies for their uninterrupted operation. The overheating of switchgear equipment continues to be a factor responsible for the majority of installation failures. Almost all swtichgear standards
  • Success Stories- Vacuum Switchgear
    . In this application the Vacuum switchgear are connected to the overhead lines. or substation bus by air insulated bushings. A conductor and a shield electrode. are fixed inside the bushing. The three polo interrupters are respectively placed. inside metal enclosures.
  • High Voltage Switchgear, Sulfur Hexafluoride & Moisture Issues
    Moisture in Sulfur Hexafluoride (SF6) an insulating gas can cause rapid and severe deterioration of high-voltage switchgear. During electrical power distribution at transmission voltages (ranging typically from 100 to 400 kV), power switching or load current. interruption is a major problem
  • Infrared (IR) Window Installations into Medium Voltage Switchgear
    The intense energy and duration of an electric arc flash represents a very unique exposure. Everyday work clothes made from regular cotton or polyester cotton blended fabrics, regardless of weight, can be readily ignited at some exposure level. Once ignited, the clothing will continue to burn adding
  • Data Center Implements Infrared Inspection of Critical Switchgear
    At IRISS, we provide our customers unsurpassed quality at every touch point. We focus on what we do best by continuously improving infrared (IR) window technology, building reliable products, exceeding customer expectations, remaining a science-based R&D company, and protecting our polymer IR
  • Repair or Replace Your Switchgear Lineup: Four Things to Consider
    Repair or replace? It's a question repeatedly faced by plant engineers and maintenance managers. For power distribution equipment, there are four important considerations when making that decision.
  • Wireless Switches Input KanBan System
    A ?Wireless Kanban? system based on remote control switchgear gets to work in Salzburg's renowned ski production.
  • A Multi-Tenant Commercial Office Building in New York City, NY. Part 2 Case Study
    This proactive client wanted to monitor the electrical panels and disconnects in the Main Switchgear Room of the facility daily versus annually. Delta T Alert's installed on panels and disconnects in the Main Switchgear Room of this facility. The Delta T units. were programmed to record temperature
  • Can IR Viewing Panes Carry an Arc Rating?
    Electrical switchgear comes in infinite shapes and sizes and as such the surface areas and volumetric. elements of the cabinets are different with each model, type and rating. Switchgear companies design. panel enclosures to contain and survive differing levels of arc flash energy that may
  • Infrared Window Installation Hints and Tips
    Once the infrared windows are installed, we will use infrared inspections to inspect the switchgear and the results from these inspections are then put into reports. Many infrared cameras do not have a digital camera and the windows do not normally allow for clear visual images due to issues
  • Infrared Window Material Choices
    Manufacturers have used Infrared (IR) windows in motor control centers (MCC) and electric switchgear. for over two decades. Here is a listing of some of the IR lens materials that are used.
  • What Certifications are Relevant to Infrared Viewing Panes?
    Currently, specific certifications for infrared window by a recognized body (UL, IEEE) do not exist. The following certifications are used by manufacturers to provide confidence that the IR Viewing Pane is suitable for use in Electrical Switchgear and Motor Control Centers.
  • Preparing for Infrared Window Installation Hints and Tips
    It is important to take the opportunity of standardizing the emissivity of the components within the switchgear that you wish to inspect through the Infrared window. This can be done using Glyptol TM Paint, electrical tape or IRISS IR-ID high Emissivity Target Labels.
