Isolation Transformers

Sourced and supplied across Saudi Arabia

An isolation transformer is bought for what it separates, not for what it converts, and that is why a kVA figure alone is never enough to quote against. The ratio is usually one to one. What the buyer is actually specifying is a galvanic break: a supply whose secondary has no reference to the site earth until you give it one, so that a single earth fault on a sensitive circuit does not trip the source or put fault current through an instrument reference. State the reason and the right unit follows. Separating a noisy drive from an analyser needs an electrostatic screen between windings and a stated coupling capacitance; creating an unearthed IT system for a control room or a test bay needs a double-wound unit with insulation monitoring; separating a portable tool circuit is a different, simpler product again. Tell us what problem the separation is solving and where the secondary earth reference will be made.
