Applied voltage indicator for current converter - has insulating housing contg. prim. conductor, sec. coil, discharge lamp feeding remote indicator via light conductor

摘要

The arrangement contains a primary conductor (2), pref. in the form of a rod, rail, collecting bar or similar, a secondary coil (6) with one or more iron cores (5), a capacitive divider (7) and an insulating housing (1). A discharge lamp (13) for visual indication of the applied voltage is connected to the capacitive divider via an electronic circuit (11) and mounted in an aperture in the housing. The lamp is coupled to a light conductor (22) leading to a separate indicator element (25). USE/ADVANTAGE - The arrangement enables safe indication of voltage over large distances irrespective of the type of measurement or current converter.
