Isolation transformers and autotransformers solve two distinct problems associated with alternating current: galvanically isolating two circuits and matching voltages between 115 V and 230 V systems.<\/p>\n
To electrically isolate the installation from the power supply. In boating, this is the solution to the problem of the galvanic corrosion in a harbour<\/strong>: when the boat is connected to the jetty\u2019s earth terminal, the hull becomes electrically connected to those of neighbouring boats and the return currents corrode the anodes.<\/p>\n The transformer cuts off this path: the vessel receives power without sharing a ground reference. It also provides protection against indirect contact in mobile installations.<\/p>\n An autotransformer steps the voltage up or down without insulation, using a single winding. It is used to operate between systems of 120 V and 240 V<\/strong>, typically on US-built vessels arriving at European ports, or to create a neutral in split-phase systems.<\/p>\n It is not a substitute for an isolating transformer: it steps the voltage up or down, but does not isolate the earth. If you\u2019re looking to prevent galvanic corrosion, you\u2019ll need an isolating transformer.<\/p>\n All models are from Victron Energy<\/a>, from 2,000 W to 7,000 W. Not sure which one you need?
