Wirings & Electric Cupboards Control

The infrared camera is the tool to control your wirings and electric cupboards without any contact. Quick and safe method, defaults are localised in a few minutes.

Let present some examples from industry:

This picture shows an abnormal heating for one of three cables. (cf "Li1") We can easily notice a difference of temperature about 30°C. It must be repaired before 7 days.

We can see above a case of danger: one of three conductors from this fuse cutout is warming over 140°C. It must be changed as soon as possible.

Another overheating example: this resistance could not be made for this use. It must be changed or removed as soon as possible.

Soot upon plugs may cause overheating too. We can see it on these relays. It is not urgent to change but it must be done before three months.

There are many other overheating causing cases like bad ventilation, a too low gauge circuit breaker, defective connections, a bad dimensioning cables/load, etc... All these defects are detectable and measurable with infrared thermography.

Nuclear Powerplants: Controlling the Pressurizer (PZR)

Vue d’ensemble d’un Pressuriseur

The pressurizer is a major element of a nuclear powerplant which used to maintain a constant pressure of 155 bars inside the primary circuit. Corresponding to a saturation temperature of 345°C, this pressure prevents water to boil inside the primary circuit.

The pressurizer is a vertical cylindrical tank with two hemispherical ends and an electric heater bundle at bottom. His top is equipped with a water spray nozzle and expansion pipes.

This equipment must be fully operational because it controls the pressure regulation and it maintains water/steam balance inside the pressurizer.

It is useful to control distribution boxes and penetrations associated with electric heater bundle to detect connections overheating.

Bellow: an overheating point inside a distribution box (SP1 point to 84°C). The difference of temperature between two checked points is over 28°C.
