APPLICATION OF INFRARED THERMOGRAPHY TO ELECTRICAL DOMAIN
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:
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)
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.
