About Isolation Transformers
Isolation Transformers are units with electrical separation between primary and secondary windings to provide isolation between either source or load and ground. These products also provide isolation between load and source.
A high voltage isolation transformer is designed to have input and/or output voltages that are significantly higher than common line voltages. These are designed and tested to a higher dielectric test voltage than the operating voltage it is designed to produce.
High Voltage Isolation Transformers are highly insulated from primary to secondary and secondary to ground. These units are used to isolate the high voltage components from the rest of a system and may be incorporated as part an electronic assembly or be used as a separate unit to isolate an entire “hot deck” or electronics operating area.
Quality Transformer and Electronics' is capable of designing and implementing an electrostatic shield, air, FS6 gas (sulferhexaflouride), oil, and epoxy-cast coils in order to meet our customers' desired isolation needs. Isolation provided by Quality Transformer and Electronics' transformers can help protect against shock, suppress noise to help protect equipment, and improve power quality. If your application requires a very high level of isolation and good overall power quality, refer to Quality Transformer and Electronics' line of Noise Cut Transformers (NCT), Isolation Transformers, and Power Conditioners. For Ultra High Isolation, please refer to our Power Conditioners and Noise Cut Transformers.
