Disclosed is an electrically heatable transparency (10) comprising: a non-electrically conductive substrate (12); a first bus bar (22) on a surface of said substrate (12); a second bus bar (24) on said surface of said substrate (12) spaced from said first bus bar(22); an electroconductive heating member (18) on said substrate (12) interconnecting said first and second bus bars (22, 24); and means (48) to detect voltage in said electroconductive heating member (18) at a location intermediate said bus bars (22, 24), a method for monitoring the current to said heatable transparency and a control for monitoring the current to this transparency. 1 |
