HIGH VOLTAGE TRAINING Purpose: Target groups The e-learning module is designed for theoretical training of engineers in Engine - Management accordance with Chapter III of the STCW Convention in the part concerning Engine - Operati°na| operate and maintain power systems in excess of 1,000 volts. Ship types Generic What is an e-learning module? E-learning module is the electronic textbook on one or more sections. Theoretical materials can be accompanied by drawings, diagrams, photos, animations and videos. There is a test for assessment of knowledge gained at the end of each section. Contents: • Introduction • Definitions • Description of ship high-voltage systems • Dangers when working with high voltage equipment • Emergency response • Risk mitigation procedures when working with high voltage equipment • The composition of the ship's high-voltage system • Safe placement of marine high-voltage equipment • Safety rules when working with high-voltage equipment • Safety measures when working with ship high-voltage equipment • Application of protective equipment used in high-voltage installations
