Inspection windows are an electrical maintenance safety device. They provide a convenient and safe way to monitor the internals of the transformer cabinet. Namely, the gauges and bushings.Â

If you’ve already got a transformer on-site, you can still install viewing and IR windows. It’s a fairly straightforward process.

If you’re installing a viewing window, make sure it’s placed so you can effectively see what you need to monitor visually. Place the window where you can read the pressure vacuum, liquid level, and/or temperature gauges.

An infrared (IR) inspection window allows light energy to pass between the inside and outside of the cabinet. This is key for measuring the temperature of the transformer’s bushings and other components inside the cabinet. These windows are commonly made of crystal, not glass. It is important to consider the placement of the IR window. It should be located where a heat gun can easily point at the bushings. The gun will give you an accurate temperature reading of each bushing. And, you don’t even have to open the cabinet.

The PM-2000A is suitable for a digital cinema projector installed on a pedestal. The stand can be adjusted from 750mm (29.5 inches) to 1,495mm (58.86 inches) to fit a projector with different height levels. It is slim and lightweight (less than 15kg; 33.07 pounds) for installing in different projection booths. The PM-2000A offers modular parts, a simple connection, and a fan-less design for easy installation and maintenance.

Without opening the cabinet, you can check the fluid level, temperature, and pressure gauges. You can also inspect the bushings and cable terminations. But, you won’t be able to take a heat reading through the glass.

Unlike the infrared option, viewing windows allow visual inspections only. Providing visual checks inside the cabinet. Viewing windows are typically glass instead of crystal. Some viewing windows are made of more durable materials, especially for industrial applications where broken glass would pose a significant risk.

Inspection windows come in a few different styles. In this article, we’ll cover the different versions and installation considerations for each.

You can strategically place the IR window so that you can see the gauges through it, too. If so, you won’t need a separate viewing window to check gauges.

Transformers have monitoring devices such as gauges, sample valves, and test ports to help identify issues in the transformer before they become critical.

The Espedeo PM-2000A is a standalone polarized 3D system developed for digital cinema projectors supporting high frame rate (HFR) content in 48 and 60 frames per second per eye. The PM-2000A has multiple coatings that helps to project bright, clear images by precisely and efficiently varying the polarity of light passing through it to help eliminate ghosting. The PM-2000A is designed for easy operation by detecting 2D and 3D signals, which enables the system to shift corresponding working positions automatically.

IR windows provide both thermal and visual monitoring options. For this reason, they are an ideal choice. But, if you don’t need thermal monitoring, viewing windows work great. Viewing windows may also cost less. They are the perfect choice for monitoring the open and closed positions of mechanically operated switches.

Monitoring your transformer is key to safe and efficient operation. But it can be an involved task. Part of the difficulty is that routine inspections often occur while the transformer is under load. This exposes workers to potential arc flash risks, calling for special PPE. Inspection windows provide a way to monitor without having to open the transformer cabinet. This helps workers more easily comply with electrical safety requirements. It also may remove the requirement for certain PPE during routine inspections.

IR windows also work with thermal imaging cameras. A thermal imaging device gives you an overall picture of heating around the tank and bushings. It also gives some information about the unit’s overall operating temperature. This can help identify unusual hotspots. Hotspots at the bushings can be caused by loose or faulty connections. Finding and correcting such issues early prevents catastrophic failures later on.
