Technical training
Basic Technical Training Standard / V11 10032026
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:
a.
situation where there is no PE, no GFCI/RCD
b.
situation where there is PE, no GFCI/RCD
c.
situation where there is both PE and GFCI/RCD
Facilitate a learning activity such as asking the participants 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
Explain and demonstrate how to identify double isolated tools including that they do not require grounding
Facilitate a learning activity such as asking the participants questions about how to identify double isolated tools
Show the importance of grounding an external generator in accordance with the manufacturer’s user manual, local legislation, and company rules
Show examples of the symbol of the GFCI/RCD and PE
Emphasise that not all circuits on a wind turbine are protected by GFCI/RCD’s
Lead a discussion with the participants about examples of what to do when encountering circuits that are not protected by GFCI/RCD’s
Explain the relation between current and contact time
Ask the participants involving questions about the relation between current and contact time
Show the consequences of getting a shock from a circuit protected by a GFCI and on a circuit without GFCI
Ask the participants involving questions about the consequences of getting a shock from a circuit protected by a GFCI and on a circuit without GFCI
Test the participants´ attitudes and understandings about PE AND GFCI/RCD (e.g. through a multiple choice test, exercises, scenario-based questions or a questionnaire about PE & GFCI/RCD)
Give constructive feedback to the participants’ performance throughout the activities of this element with an emphasis on encouraging the participants to always use PE and GFCI/RCD when applicable
