Staggered through-field electrode

The staggered through-field electrode system is also arranged as an array of electrodes but located alternately below and above the pro-... 

With the stray field type, the load, usually in the form of a thin web, passes over the electrodes of alternating polarity. Since the load represents the path of least electrical resistance, the dielectric field passes through it, causing heating. The staggered type is usually used for sheet materials and thick webs. The distance between the electrodes is kept to a minimum in order to achieve heating without arcing.
