Abstract
In a complex industrial installation, it is usually very difficult to locate the position of a fault when one occurs. In a method of determining the location of a fault, information corresponding to each component part of the installation and the correct operating parameters of each component part is stored in a memory and a computer is used to produce on a visual display unit schematic diagrams of at least part of the installation and indicates tests which are to be carried out, the operator causes the test results to be supplied to the computer and, after comparing the results with the stored information, the computer indicates on the display either where the fault lies or further schematic diagrams and tests which are to be carried out to locate where the fault lies. Apparatus for carrying out the fault location is also described.
