Profile: General Transformer Corp. is a manufacturer of transformers and inductors. Our products include ferroresonant transformers, toroidal transformers & inductors, three phase transformers and laminated steel transformers & inductors. Our inductors are useful in both AC and DC circuits. Our ferroresonant transformer is used as a line conditioner to protect computers and other sensitive electronic devices from transients, noise & surges on the power line. Our toroidal transformer is made from a long strip of silicon steel or permalloy wound into a coil, powdered iron, or ferrite. Its strip construction ensures that the grain boundaries are optimally aligned, improving the transformer's efficiency by reducing the core's reluctance.
