SPANNUNGSMESSGERÄT FÜR HOCHSPANNUNGSELEMENT

摘要

The device (10) has an oblong printed circuit board including an insulating layer (12) and a conductive layer (11) connected to ground potential. The printed circuit board has another conductive layer (13) formed of separated conductor sectors (14-17) that are connected in parallel to a control equipment (25) and an optical luminous display (26) i.e. LED display, via signal output cables (20, 21), respectively. The printed circuit board has contact bridges that connect the conductor sectors to the corresponding signal output cables. An independent claim is also included for a gas insulated electric substation comprising a capacitive device for measuring voltage of a high voltage element.
