The permittivity of an ideal dielectric is independent of the magnitude of an applied electric field; the material is said to be "linear." 1 However, all practical dielectrics fail in this respect with sufficiently strong electric field. Grounding is also a very common way to handle and should be coordinated with electrical. NFPA 82 NBC We're doing some work at a hospital, in particular, some MRI rooms. This technique has been in use for the past 40 years but has been superseded by even more advanced techniques in the last 25 or 30 years. H|TQO0~G)I!D)LB.
