Characterization of closed-doors electrical cabinet fires in compartments

Characterisation of open-door electrical cabinet fires in compartments

“…A model for describing a complex fire source (see Paragraph 4) is developed, applied for open-door electrical cabinet fires and used to perform calculations with SYLVIA code for fire scenarios carried out in confined/ventilated compartments. This paper complements the paper published previously (Plumecocq et al, 2011) on the characterisation of closed-door electrical cabinet fires in compartments.…”

“…Recently, IRSN (Plumecocq et al, 2011) conducted experiments on closed-door electrical cabinets burning under a calorimetric hood and inside a mechanically-ventilated compartment. An analytical approach was used to investigate the effects of materials (PMMA, mixtures of polymers), of cabinet vents (sizes and locations), steel walls of the cabinet and oxygen depletion inside a cabinet on the HRR.…”

Energy balance in a confined fire compartment to assess the heat release rate of an electrical cabinet fire

“…The heat release rate with the PYROS gas burner system is therefore experimentally determined based on both a simplified thermal method and the measurement of propane flow rate supplying the burner, as previously described in Section 3.3. The temporal evolution of the heat release rate is calculated using the thermal method (12) and then compared in Fig. 6-a with that determined using Eq.…”

“…As a first step, the IRSN developed an experimental program to study electrical cabinet fires based on an analytical approach ( [10]) consisting of investigating the effects of combustible material content (PMMA, polymer mixtures), door position (open or closed) and opening size and location (closed door only) on the heat output of the fire. The lack of published data and the difficulties of transposing such experimental results to actual electrical cabinets led the IRSN to propose a second experimental program to study electrical cabinet fires in a free atmosphere ( [11]) and, subsequently, in a confined and mechanically ventilated environment ( [12]). This program aimed to address safety concerns regarding the consequences of an electrical cabinet fire in a nuclear facility, and also provided relevant input data (cabinet fire load in particular) for assessing such fire scenarios based on fire codes.…”

Recursive construction of output-context fuzzy systems for the condition monitoring of electrical hotspots based on infrared thermography

“…These conditions tend to occur in old buildings with outdated and deteriorating electrical wirings or electrical wirings that are inappropriately amended or insufficient for the electrical load. However, newly constructed buildings are not immune to these conditions (Plumecocq et al, 2011;Babrauskas, 2001). …”
