Patent GB-1219268-A (GB)
Title: Electric current measurer
Inventor: EVANS BRIAN ARTHUR
IPC: G01R15/24
Filed: 1968-01-26
Abstract: 1,219,268. Current measurement. MULLARD Ltd. Jan. 24 1969 [Jan. 26, 1968; Nov. 19, 1968], Nos.4232/68 and 54879/68. Heading G1V. A current measuring system for use with large currents on a high voltage conductor incorporates a search unit incorporating a secondary winding on a magnetic core surrounding the conductor which provides an output which is used to energize the magnetizing coils of two or more Faraday effect devices. The actions of all the Faraday devices on a plane polarized light beam are combined to provide a beam whose polarization rotation represents the current to be measured. In one arrangement Fig. 1 the search unit incorporates a single winding 3 on a core 2 surrounding the conductor 1 and the output of this energizes two differently dimensioned magnetizing coils 6, 7 for two Faraday effect bodies 8, 9 through which a plan polarized infrared beam from a source S is passed. The plane polarized beam is additively rotated by each of the coils 6, 7. This system provides automatic range changing, the system being particularly sensitive to small currents because of the strong magnetic excitation per ampere turn due to coil 6. When the saturation level of the element associated with this is reached however it makes no further contribution to beam rotation and the system responds in a less sensitive manner to larger currents, further rotation being produced only by the coil 7. Alternatively two separate, differently sized coils may be arranged on the core 2, each supplying similarly sized coils 6, 7 Fig. 2 (not shown). The rotations may be subtractive, the currents in the windings 6, 7 rotating the beam in opposite directions so that there is no resultant rotation until one of the elements saturates, whereafter the other causes an output to be produced. In this way the system will respond only to currents to be measured in excess of a threshold. A similar technique may be used for temperature compensation. Faraday materials with different temperature co-efficients are used so chosen that when their effects on the plane polarized beam are subtractive temperature compensation is effected. Where all the elements are the same, and their effects are added, a system of improved sensitivity results. In a system for reducing interference due to near-by conductors or steady fields on a Faraday device, two such devices are arranged side by side and an optical mirror system is arranged to reflect a plan polarized beam transmitted through one of then back in the opposite direction through the other. The magnetizing coils are wound so as to rotate the beam additively as it passes each device. Interfering fields will however produce a subtractive, cancelling effect in the two coils, Fig. 6. All the arrangements previously described may be used in this system, by associating a further Faraday device with each of the two main devices. These further devices may have their windings in series with those of the main devices or may be energized from a separate winding on the core 2. Figs. 7 and 8 (not shown).
