Description
Victron isolation transformer, 7.0kvA for nominal 32A shore cord. Supplied with soft start and with enclosure. 175 mA no load consumption. ITR000702001 – 230V/230V (32kg)
Product Information
Indispensable in professional marine energy systems. It prevents electrolytic corrosion and above all serves as a device to guarantee a safe electric system. Toroidal wound technology for quietness and high efficiency. Soft start circuitry will ensure that the shore circuit breaker will not trip when plugged in.
Models:
2000W / 3600W / 7000W
Safety and prevention of galvanic corrosion
The Isolation Transformer eliminates any electrical continuity between AC shore power and the boat. It is essential for safety and eliminates the need for galvanic isolators and polarity alarms.
Why you need one
It is a misunderstanding that galvanic corrosion occurs only in metal and aluminium hulls. In fact it can occur on any boat as soon as a metallic part (the shaft and propeller) is in contact with water. Galvanic corrosion will quickly dissolve your sacrificial anodes, and attack the shaft, propeller and other metal parts in contact with water as soon as the boat is connected to the shore-side supply. It might therefore be tempting not to connect the ground conductor: this is however extremely dangerous because GFCIs will not work nor will a fuse blow in case of a short circuit to a metal part on the boat.
Solution
The best solution to avoid galvanic corrosion and at the same time prevent any unsafe situation is to install an Isolation Transformer to connect to the shore-side supply.
The Isolation Transformer eliminates any electrical continuity between shore power and the boat. The shore power is fed to the primary side of the transformer and the ship is connected to the secondary. The Isolation Transformer completely isolates the boat from the shore ground. By connecting all metal parts to the neutral output on the secondary side of the transformer, a GFCI will trip or a fuse will blow in case of a short circuit.
It is also recommended, for optimal safety, to connect the secondary neutral of the transformer to ground when the boat is out of the water.
