What is an isolating high voltage transformer?

An isolating high voltage transformer is similar to an isolating transformer, which has a protective barrier between primary and secondary windings, but with a greater degree of protection between windings.

Isolating High Voltage Transformer

In addition, an isolating transformer is used to disconnect an appliance from the mains system completely. This is to provide a “floating” power source without any reference to earth. For instance, taking the example of a television. An isolating transformer can be used to work on a television with a non-isolated chassis, to allow the oscilloscope to be earth referenced to an area which would otherwise be at a high potential to earth.

How to order

Express Transformers and Controls (2015) Ltd have over 25 years of experience in the design and manufacture of High Voltage transformers for the scientific industry. Our team can design and build transformers isolating up to 80kVdc. These designs are produced using a vacuum encapsulation process that is capable of standing up to Class F temperatures.

Information required are the primary and secondary AC voltages and the power requirements of the transformer. We also need to know the potential, say 40kVdc on which each secondary or screen will be working at.

If you have any specific maximum dimensions please advise us on the initial enquiry.
