Ce que couvre cette vidéo
An isolation transformer prevents electric shock drowning and galvanic corrosion by electrically decoupling a boat’s AC system from the shore power pedestal.0:19 While standard shore power systems connect a boat’s ground to the dock’s ground, this shared path allows stray DC currents to accelerate the corrosion of underwater metals like propellers and shafts.6:04 An isolation transformer uses magnetic induction to create a new power source on board, ensuring that any ground fault remains contained within the vessel rather than energizing the surrounding water.6:51
For older vessels lacking this protection, installing an Equipment Leakage Circuit Interrupter (ELCI)—also known as an RCD in Europe—provides a critical safety layer by cutting power if it detects current leakage between the hot and neutral wires.3:56 A galvanic isolator offers a lower-cost alternative to a transformer by blocking DC current while still allowing AC fault current to flow.6:24 Regular inspection of shore power cables and connections remains essential to prevent hazardous ground faults.
