Course Description

Explosive atmosphere, ignition sources and explosion. Area classification and hazardous zones. Flammable materials' characteristics. Ignition energy and ignition temperature. Explosion protection („Ex“) design requirements for electrical equipment intended to be used in industrial facilities at risk of explosive atmosphere („Ex“ d, e, p, i, m, q, o, t, n). Equipment categories. Conformity assessment, certification and marking of electrical „Ex“ equipment. Electrical installations in industrial facilities at risk of explosive atmosphere. Electrical protections. Special and additional requirements. „Ex“ electrical drives. Introduction of diagnostic methods for induction motors in hazardous areas. Testing, maintenance and repair. Hazardous area risk assessment. Practical examples of real industrial facilities with hazardous zones and „Ex“ equipment. European and Croatian legislation for explosion protection – ATEX Directive. Relevant IEC, EN and HRN standards.
