Title: Leakage monitor for gas insulated HV conductor - is fitted with orifice plate and differential pressure switch to detect pressure drop in affected section
Inventor: WAGENBACH WOLFGANG DIPL ING
IPC: H02B13/065
Filed: 1975-08-28
Abstract: The conductor (1) encapsulation (2) is divided into sections (4) by bulkheads (3) spaced at intervals along the length of the run. Each bulkhead is bridged by a calibrated orifice (5) across which a differential pressure switch (6) is also connected. For small gas leakages the orifice permits gas flow to equalise the pressure between sound and leaking sections. For a large leak the differential pressure across the nearest orifice trips the pressure switch and the affected section can be indicated. Using differential switches in conjunction with an orifice permits locatisation of a serious leak, and the differential measurement cancels out any temperature effects which may cause errors in direct pressure measurement systems.
