Mobile Power Grounding Unit (MPGU)

The A-2-Sea Mobile Power Grounding Unit (MPGU) provides power safety and the ability to work on potentially live submarine and terrestrial powered cable systems during installation and repair.

The equipment facilitates the repair on non-live segments of a cable system which may become live for various reasons. By removing the need to switch off the whole system to undertake a repair, there is a significant reduction in loss of revenue during the downtime.

The MPGU equipment is low-cost, modular, lightweight and transportable. It can be used on barges and vessels of opportunity when installing or repairing submarine cables or installing and repairs from the beach to the terminal station and practically any location in between. Equipment is available to measure the ground resistance of the available earth: system, station or temporary earth created for the MPGU repair.

The MPGU is flexible, portable and adaptable, and can accommodate the whole range of cable types that exist in today’s systems. It also offers system installers, owners and planners the low-cost installation options they need.
