HigH voltage training breaker
Transas Ers 5000 TEchsim
Transas is a world leader in the manufacture of Engine room simulators used for marine engineering and electrical training. Due to an increase in the number of high voltage ships, the training programme for marine Electrical Engineers has made high voltage training mandatory. a practical element of training has been introduced requiring safety training using real equipment. This does not necessarily have to be live equipment.
To meet this new training requirement, Transas has developed a real hardware high voltage generator breaker cabinet in conjunction with power technology specialist aBB.
equipment suppliedThe breaker is compatible with the existing Transas Techsim simulators with high / medium voltage systems.
high voltage distribution systems can be used in several ship types: ■ DE cruise ship ■ steam Turbine LnG carrier ■ DE LnG Tanker.
Connection to existing simulator The breakers are supplied by the following manufacturers: aBB, hyundai, siemens and mitsubishi. The breakers are fitted with ‘earthing’ arrangements and safety interlocks. Transas offers interconnection between the Techsim simulator and any of the above high voltage breakers.
training objeCtives ■ realistic hands-on training in high voltage switchboard operations
■ Understanding safety as a personal responsibility ■ Electricity and work planning ■ identification of hazards ■ Emergency procedures and contacts / location of emergency gear
■ Knowledge of circuits / power feeds / emergency shutdown and isolation devices
■ Familiarisation with company protocols ■ isolation of breakers in ships’ electrical systems ■ Use of high voltage test equipment ■ Use of high voltage Personal Protective Equipment (PPE)
■ Definition and identification of circuit condition / energised work conditions
■ Practical assessment of personnel and assignment of work / qualification of a worker.
Designed to meet the training requirements set out in section a-iii / 1, a-iii / 2, a-iii / 6 & B-iii / 2 of the sTcW code 2010 (manila amendments).

simulator interfaceThe lower part of the breaker comprises a real breaker operated by the simulator electrical system mathematical model. The upper panel contains the instruments and controls for a typical high voltage generator. The controls and instruments are connected to the simulator model via a digital analogue interface.
To simulate LcD type Power management system controllers, a precisely developed small touch screen display simulates the controller functionality.
The simulator is connected to the breaker using a Wago cOTs automation interface which may also be used for automation training.
test equipmentFor safety reasons high voltages are not used within the training breaker. The presence of high voltages is simulated using low powered radio signals. an adjusted high voltage probe signals the presence of voltage on the bus bars using a specially adapted test probe.
personal protective equipment (ppe)high voltage PPE is supplied as a part of the training breakers equipment.
The bus ties and generator breakers are installed in the main switchboard and are normally ‘front loading’ Vacuum circuit Breakers. The electrical systems are of common design and operate at the following voltages:
■ Up to 6600 V ■ 3 phase ■ 60 hz ■ Generators 3350 to 4000 kW
a complete safe removal and replacement procedure may be conducted for training and assessment. This includes both the mechanical and electrical isolation of the generator system prior to the start of work. all tools, test equipment and personal protective equipment required to carry out the operation are supplied with the breaker. This includes a breaker cart.
