	Hi to all, my name is Armando, I am spanish and working now for my project to
finish my studies in Industrial Engineering (Electrical intensification).
        The project is about partial dischargues in insulating materiales.
        I need a pair of toroids about 50cm(20 inchs) of outer diameter and
10cm(4 inchs) more or less of diameter of the tube (similar to taps of Tesla
Coils) to make some connections inside at constant electrical field (free of
electrical dischargues).
        I don't know if exits some store or industry (better in Europe) that
make this commercially. This toroids are similar to the used in Tesla
Coils,so, maybe somebody can tell me where he bougth it.
	Thanks to all.
	Best regards. Armando-EA5GKB.
