MEASURING SYSTEM FOR ENCLOSED HIGH-VOLTAGE SWITCHGEAR

摘要

(57) The in on concerns a measuring system for enclosed high- voltage switchgear having at least two single-phase encapsulated poles (1, 2, 3) with dielectric dielectric interference sensors (5, 6, 7) and with a detector device (4) connected to the sensors in order to emit a signal in the event of interference. The measuring system comprises a time comparator (8) which blocks the emission of a signal if the time difference between two interference signals from sensors (5, 6, 7) of different phases falls short of a given time interval which is in particular adjustable.
