Definitions

• My invention relates to three wire or compensating systems of electrical distribution in which the lamps or other translating devices are arranged in multiple series, and a third wire or compensating conductor for preserving the balance of the system extends from the translation circuits to the source of supply.
• My object is to provide a system in which the greatest economy in the amount of metal required for conductors will be attained, by combining the advantages in this respect of the three wire system with those arising from the use of currents of high tension reduced at the places supplied, by induction coils or converters, to that required for the translating devices.
• A represents an alternating current d ynamo electric machine of which one or more may be used to form a source of current of very high tension.
• B is a continuous current generator for energizing the field magnets of the alternat- In this field circuit is an adjustable resistance 0 for regulating the electro-motive force of the source of supply A.
• a circuit P N extends to divided induction devices or converters for reducing the tension of the current.
• the divided converters have each two secondary coils a and a. From one secondary circuit of a converter, a conductorp' extends to the positive side 19 of the connected system; from the other secondary circuit a conductor 02' extends to the negative side n; and the two secondary coils are joined together, and from their junction a conductor 0 extends to the compensating main conductor c.
• the electric lamps or other translating devices Z) I) are connected as shown in multiple series each translating device being connected between one of the outer conductors and the compensating conductor as is well understood. By this arrangement the induction coil or converter becomes a divided source of electricity connected with translating devices in multiple series and having a compensating conductor connecting the translation circuits with the point of division of the source.
• the conductors P N from the generator A extend to suitable terminal points Within the station, whence, "from the conductor 1 conductors l" P extend and from conductor N, a conductor N extends.
• Conductor P includes the primary coils, in reces, of the two induction coils D", D; and conductor P similarly includes the primaries of D D
• the secondary coils of each pair are connected to the system of mains in the same manner as the two secondaries of the double induction coil in the other arrangement. That is, the secondary of coil D is connected with the positive side 19 of the system; the secondary of coil D is connected with the negative side it; and the two secondaries are joined together and at the junction connected by c with the middle conductor a. Divided sources of electrieityare thus formed as before.
• Conductors P and P both are connected with return conductor N.
• the two sides of the system are regulated independently to keep the system balanced by the adjustable resistances F F situated respectively in the conductors P and l? which being adjusted relatively to each other Vary the current given to D relatively to that of 1), whereby the two sides of the lighting system are kept in balance.
• Such regulation is performed in accordance with the showings of the indicators 9 9' connected respectively between P and N, and P and N which show the pressure on each side of the system at the centers of consumption where the converters are placed.
• What I claim is- In a system of electrical distribution, the combination of a source of current of high tension, two feeding circuits extending therefrom, each including the primary coils of a tension reducing converter, a circuit including translating devices in multiple series, a conductor from the secondary of one converter extending to said translation circuit, a con ductor from the secondary of the converter in the other feeding circuit, also extending to said translation circuit, a conductor extend ing from between the translating devices to one joining the two secondaries, and means for separately regulating the two feeding circuits, substantially as set forth.
