Practical Marine Electrical Workshop (PMEW)
Covering advanced aspects of shipboard electrical knowledge, this workshop, conducted in a dedicated laboratory, provides theoretical information, intensive hands-on training and group discussions leading to improvement in competence and confidence in handling and troubleshooting electrical equipment.
The participant is exposed to intensive practical training, both, in actually wiring up several types of starters and also in troubleshooting faults induced in them.
Extensive tracing of various different types of electrical circuits of shipboard machinery is carried out. This helps the participant to gain confidence in his ability to trace complex circuits.
Practice on a fully equipped and functional Boiler control panel further develops his ability to trace circuits, locate and rectify faults induced therein.
Course Objective:To enable the participants to:
- understand the fundamental concepts of electrical technology.
- recognize component symbols and their construction, functioning and applications.
- identify symbols, trace and analyze circuit diagrams and troubleshoot electric systems logically.
- learn through sharing of experiences amongst participants.
