Effect of Electrode Shape on Progress of Electric Discharge

Original language description

Minimum ignition energy (MIE) is determined as a one of the parameters when assessing the hazards of a given dust sample. This value indicates the sensitivity of the given sample to electrostatic energy. The legislation determines the procedures and the requirements for the equipment used to determine the MIE. Among other things, it lists requirements for the electrode used such as its material, diameter and pointed spike shape. The ČSN EN ISO/IEC 80079-20-2 standard valid on the territory of the Czech Republic also provides the possibility of using a rounded electrode spike. This formulation leads us to the question of whether the shape of the electrode spike can affect the electric discharge progress and in what way. Within the sequence of measurements carried out, a detailed examination of the impact of the electrode shape on the formation of electric charge was provided, using the MIE-D 1.2 apparatus. Four different electrode spikes shape were used, together with a high-speed camera able to take 210,000 pictures per second. The results show that from the four types of the electrode spikes, the fastest electrical discharge is occurring when a standard pointed spike is used.
