High Voltage Safety and Switch Gear Course (D. G. S. Approved)
Operators of such equipment require to be well trained in all aspects of High Voltage Safety.Modern ships, particularly Container, LNG, Passenger and specialized off shore ships are built with high voltage generating plants of 3.3 KV, 6.6 KV and 11 KV.
The course includes practical hands-on exercises on an actual High Voltage Panel comprising of Vacuum Circuit Breaker, Earthing switch along with the associated interlocks, Potential and Current transformers, Bus Bar chamber and Low Voltage Safety Relay panel, thus familiarizing the participants with High-Voltage switchgear and the various safety procedures for handling the same.
The training provided meets the provisions(for high voltage training) as mentioned in Section A/lll-l, A/lll-2, A/lll- 6 & Blll/2 of the STCW Code 2010 (Manila Amendments).
Course Objective: To enable the participants to:
- Satisfy the requirements of STCW 2010 (Manila Amendments) and attain higher competence level in safety awareness and technical competence in handling HV installations.
- Understand the working of the various specialized components equipment and switchgears used in High Voltage installations.
- Operate, maintain & troubleshoot High Voltage installations safely & efficiently.
- Learn through sharing of experience amongst participants.
