Towards an hypertext of electric measurement: different approaches for an on-line, remote, didactic lab.

Hypertexts are becoming a promising solution in educational activities, since they allow to integrate, in the same product, different ways for presenting a specific topic: traditional text and drawings, animated pictures and graphics, video and audio clips, interactive exercises and simulation though lab classes are extremely important when teaching measurement issues, up to now these solutions do not allow direct access to experimental activity involving the use of real instruments. This paper proposes different solutions for integrating a remote laboratory in a hypertext of electrical measurement and shows how they have been implemented in the realization of a remote experiment on a three-phase three-terminal load
