required to supply high voltage power to the ROV and TMS system a HV transformer a transformer is typically used to step up or step down the voltage levels to match the requirements of the ROV and TMS system b Grounding system c Vessel Supply d Current Transformer 2 Why do we use high voltage power a To keep conductors small and prevent drawing a huge current When the voltage is increased the current required to transmit the same amount of power decreases This allows for the use of smaller conductors which reduces costs and minimizes power losses due to resistance b Only HV power can drive an Eletric HPU motor c To prevent excessive loss of voltage through the Umbilical wire d Because it is safer 3 Which of these statements are correct Isolation devices a prevent the transmissionrelease of energy b isolate areas of the system Isolation devices such as switches or circuit breakers are used to isolate specific areas or components of an electrical system They are designed to disconnect the power supply preventing the transmission or release of energy to those areas c are ungrounded supply conductors d must be lockable with padlock or similar device 4 We couldnt work without high voltage and we cant work safely without everyone having a good understanding of it Which of the following statements is correct a High voltage has an electrical potential large enough to cause injury or demage High voltage power has the potential to cause injury or damage due to its higher electrical potential It is important for individuals working with high voltage systems to have a good understanding of the associated risks and safety measures to ensure safe working conditions b The only power supplied by our vessels is HV c Subsea 7 defines HV as being anything above 1000V AC or 1500V DC d High voltage transformers are used to stepup and stepdown power to required voltage or current 5 Where can you find more information on ROV HV electrical systems a Wikipedia b Technical manuals Because this documents are specifically created to provide detailed information on the operation and maintenance of systems including HV electrical systems used in ROVs c Company procedures But the specialized companies in ROV operations often have their own standard operating procedures and guidelines for handling HV electrical systems These procedures can provide valuable information on best practices safety protocols and specific considerations related to the equipment used d Ask a friend 6 Where are you most likely to come into contact with HV a PDU Main incoming circuit breaker The PDU Power Distribution Unit is responsible for distributing electrical power within a facility or system The main incoming circuit breaker within the PDU is where the high voltage power enters the distribution system Therefore during maintenance operations or troubleshooting activities involving the PDU there is a possibility of encountering high voltage components or equipment b ROV termination box c TMS Eletric Motor d Topside transformers 7 Which of the following onboard devices are involved in the distribution of high voltage electricity Drag and drop the items onto the
