Unitest Marine Simulators as a world leader in creation of maritime training software and engine room simulators made a step forward to meet the new training requirements as set out in STCW 2010 Table A-III/2 for electrical, electronic and control engineering at the management level in high voltage (HV) power systems training and education. Unitest has developed a real hardware high voltage generator breaker cabinet which can be interfaced to the Unitest Fulll Mission Simulator.

Training Objectives
- Practical hand-on exercises on an actual High Voltage Panel;
- Isolation of breakers with the associated interlocks in ship’s electrical systems;
- Identification of circuit condition / energised work conditions;
- HV/LV Distribution Systems and Protection;
- Knowledge of the procedure to use high voltage test equipment and Personal Protective Equipment (PPE);
- Dangers of contact with electricity and electric shock prevention;
- Precaution when performing maintenance or inspection;
- Knowledge of the procedure of issuing permits to work;
- Understanding system layout and distribution arrangements;
- Generator Synchronization.
Equipment Supplied
The High Voltage breaker is compatible with the Unitest DE3D simulator with high / medium voltage systems. High voltage distribution systems of 3.3 kV, 6.6 kV and 11 kV can be used in various types of ships, such as Container vessels, Tankers, Gas Carriers, Cruise liners and specialized off shore ships.
Compatible with the existing UNITEST simulator
The breakers are supplied by ABB and fitted with earthing switch which is controlled from the front of the module by means of a manual operation appropriately interlocked with the circuit-breaker’s position. That makes Unitest HV simulator a great tool to increase the knowledge level on various standards pertaining to safety working practices on High Voltage systems. All operations done on HV breaker will have an influence on the main switchboard in the simulator.
