Power POD main features • hosts the portion of power system able to distribute the power coming from the JB to the users. • The users are: 14 floors, and all the local electrical loads located in the Base Power Pod (BPP), Base Electronic POD (BEP) and base Optical POD (BOP), external instrumentation included. • All the distribution lines are remotely switchable except for the local line that feeds the control system. • The communication between the local control system and shore is realized through a FCM board (located in the BEP) via optical fibres. • The Power Supply System (PSS) board e the Power Control System (PCS) boardare located in the PP. • The PSS allows voltage conversion from 375 V, delivered by the JB, to low voltages required by all the electrical loads. • The PCS allows monitoring and control of: V at the input and I of all the distribution lines, T and remote switch actuation. • In case of communication loss between PCS and FCM, the PCS guarantees the output lines feeding, thanks to a time-out system that automatically actuate all the switches of these lines. • The BPP will be oil filled, all the electronics components present inside it withstand oil bath.

PSS - Power Supply System Board features The Power supply Board converts the 375V to a series of low voltages required by the users, its main features are listed below: • Working environment: oil bath, • Protection against input transient overvoltage, • 12V, 5V, 3.3V, 1.8V, 1.2V output voltages, • Soft start outputs (3.3V, 1.8V, 1.2V), • Flexible start up output sequencing, • 375 V input line current and voltage monitoring, • 5V output line current monitoring, • 50 W maximum total outputs (included DC/DC conversion losses), • Low output voltage ripple, • 12V isolated power supply for oceanographic instrumentation.

PCS - Power Control System features • Working environment: oil bath, • Working voltage 375V DC, max power 5 kW, • Distribute power to up to16 output lines, • Monitoring of input voltage and current of all output lines, • Monitoring of ambient parameters: temperature, • Remotely operated switches in all the output lines with a soft start system (100ms controlled voltage ramp), • Communication interface between PCS and the system via isolated asynchronous serial RS232, • Output short circuit protection. In case of an output line fuse blow up, the 375 V return will be opened to completely isolate the output load affected by the fault, • Time-out system that automatically actuate all the switches of the output lines in case of communication loss between PCS and the system, • Output lines current threshold remotely settable, • Autonomous switch off for over current threshold.

Test of ‘equivalent JB’ at full load + 1’equivalent tower’ SCOPE of the TEST: verify JB and Tower PCS boards and PSS boards functionality with long cables and different loads conditions. Measurements of electrical parameters with the operational voltage (375V) of all the feeding lines of JB and Towers. Short circuit test. Time out tests. Rosanna Cocimano
