ELEMENT 5.3 - PE AND GFCI / RCD
Learning objectives:
The participants can describe the function and importance of GFCI/RCD and PE in a WTG environment (Knowledge, basic level). The participants can describe how to identify double isolated tools and including that they do not require grounding (Knowledge, basic level). The participants can recognise the importance of grounding an external generator in accordance with manufacturer’s manual, local legislation , and company rules (Knowledge, basic level). The participants can recognise examples of the symbol of the GFCI/RCD and PE (Knowledge, basic level). The participants can recognise that not all circuits on a wind turbine are protected by GFCI/RCD’s (Knowledge, basic level). The participants can recognise the relation between current and contact time (Knowledge, basic level). The participants can recognise and compare the consequences of getting a shock on a circuit protected by a GFCI and on a circuit without GFCI (Knowledge, basic level). The participants show interest in always using PE and GFCI/RCD when applicable (Ability, basic level).
The instructor shall:
Show different situations from a WTG environment where a tool is used without protective earth and GFCI/RCD and with the consequence of improper grounding on tools or equipment:
Situation where there is no PE, no GFCI/RCD.
Situation where there is PE, no GFCI/RCD.
Situation where there is both PE and GFCI/RCD.
Ask the participants involving questions about the different situations where a tool is used without protective earth and GFCI/RCD and with the consequence of improper grounding on tools or equipment. Lead discussions with the participants about the function and importance of GFCI/RCD and protective earth in tools and equipment.
