Is the isolation transformer intended to isolate the ground?
The isolation transformer is not intended to isolate the ground so it is grounded and bonded as usual. It’s purpose is to isolate the primary and secondary systems from transmitting noise. I see nothing in the question that indicates what problem is to be solved.
How are EMI control devices influenced by grounding?
EMI Control Devices and Techniques. The performance of some EMI control techniques or devices may be significantly influenced by grounding. In particular, cable shields; isolation transformers; EMI filters; ESD, lightning, and EMF protection techniques; and Faraday shields must be properly grounded so as to provide maximum EMI protection.
Can a secondary transformer be hooked up without grounding?
If the secondary voltage is one that is required to be grounded by 250.20, then there is no code compliant way to hook-up the transformer without a connection between the primary and secondary EGCs (with some rare exceptions, for example the isolated systems permitted in Article 517).
Why was the emphasis on grounding in electrical design?
As a result, strong emphasis was placed on earth grounding of electrical equipment, and the overall philosophy was “ground, ground, ground” without regard to other problems, such as EMI, that may be created by this approach. When electronic equipment was introduced, grounding problems became more evident.
Where does the pen conductor go in a isolation transformer?
Once inside your house, the PEN conductor is separated into neutral and earth inside your consumer unit / distribution board aka fuse board.
How big is the isolation transformer in a shoe box?
This isolation transformer is about the size of a shoe box, will be plugged into a receptacle and will be sitting on the floor near the equipment to be protected. Any advice will be greatly appreciated. What is the sensitive electronic equipment? How is it known that an “isolation transformer” will solve whatever problem exists?
