Title: Method of testing insulation and pinpointing faults in an electrical apparatus and the application of said method
IPC: G01R31/50
Filed: 1971-06-02
Abstract: 1354984 Locating insulation faults BBC BROWN BOVERI & CO Ltd 2 June 1971 [4 June 1970] 18696/71 Heading G1U A method of locating an insulation fault in a secondary winding on a transformer comprises the following steps: (a) applying a steadily increasing potential across the windings and noting the potential when a discharge at the fault occurs (b) reducing the potential across the winding until the discharge is extinguished (c) raising the potential to within a small amount #Ui below the potential Ui at which discharge occurs. (d) applying a potential between the winding and the core to which the discharge takes place and noting the potential Ukomp at which the discharge restarts. It can then be shown that the ratio of #Ui to determine the relative position of the fault along the winding. The simplest implementation of the method is shown in Fig. 2. A potential Ep applied to the primary winding causes a potential Up to be induced across the secondary winding, the lower end of the secondary winding being earthed via an adjustable voltage source 19, set at this time to zero volts, and Ep is varied to determine Ui, the potential across the secondary at which a discharge between a point X on the secondary and the coreX' occurs. Ep is then reduced until the discharge is extinguished, and then raised so that the secondary potential is Ui-#Ui. Finally, the source 19 is adjusted to apply a steadily increasing potential between the winding and the core to determine the potential Ukomp at which the discharge is restarted. Several modifications are described. Instead of setting the potential across the winding to Ui -#Ui at which a discharge has just not started, it could be set to a value at which the discharge has just not been extinguished. Further, instead of inducing a voltage across the windings by energizing the primary winding, a potential could be applied directly across the winding as in Fig. 6, (not shown). Finally, all four of these possiblities could be modified as in Figs. 10 and 11 (not shown) by adjusting the phase of the voltage used to initiate the discharge referred to in step (d) above, rather than its amplitude. In this case the determination of the faulty point requires the solution of a quadratic equation, rather than the evaluation of a simple ratio.

Abstract: 1,188,712. Welding by pressure. SUMITOMO KINZOKU KOGYO K.K. 24 April, 1967 [23 April, 1966], No. 18843/67. Heading B3R. A pressure-welded metallic article is treated by fusing the article through a part of the thickness thereof in the welded region which has an anisotropic fibre structure, the fusion being on one side only to a depth of at least 2 mm. but not more than <SP>2</SP>/ 3  of the thickness of the article or on both sides to a depth, for each side, of at least 2 mm. but not more than <SP>1</SP>/ 3  of the thickness of the article. Such fusing causes the structure of the welded region, initially having a fibre flow perpendicular to the direction of fibre flow in the base metal and having a concentration of impurities, to exhibit a cast structure. The article, e.g. a pipe may be made of carbon steel, alloyed steel, copper, aluminium, and copper-aluminium alloys and may be made by high frequency or low frequency resistance welding, by high frequency induction welding or by forge welding. The fusing may be effected by inert gas-shielded tungsten arc, plasma arc, electron beam, high frequency induction or gas-welding apparatus which does not supply additional metal. In an example, a tube blank of open hearth steel is formed into a butt-welded tube by 450 kc./sec. electric resistance welding and subsequently treated by an argon shielded tungsten arc apparatus to fuse part of the welded region and then normalized by heating at 900 C. and air-cooled. The tube has a wall thickness of 5À9 mm. and fusion is carried out according to the invention to depths of 2 and 3 mm. In a production line the pressure welded piping is cut into lengths and subjected to fusion, flash removing and normalizing and a number of fusion apparatuses may be employed in parallel.

In an optical inspecting apparatus for detecting deviations in material being inspected wherein the material M is passed between a lamp 2 and a photo-tube 1 so that a momentary change of light falling on the photo-tube produces a signal pulse, the lamp 2 is supplied with power by a circuit which is controlled in response to the steady current through the photo-tube 1 so that a decrease in the steady current through the photo-tube results in an increase in the current supplied to the lamp. By this arrangement, the apparatus produces a constant signal pulse despite variations in operating conditions such as changes in temperature, deterioration of the photo-tube or light source and collection of dirt on the phototube, lamp and optical system. The invention relates particularly to systems employing photomultiplier tubes and is described with reference to an apparatus for inspecting yarn wherein a photomultiplier is connected to a constant voltage source and the voltage developed across a resistor in its cathode circuit is used to control a tetrode which acts as a variable resistance controlling the supply of power from a radio frequency oscillator to the lamp. Specification 860,271 is referred to.
