The secondaryicoil, in which the current is proportional to the sum of the currents in thetwo primary coils, is connected to the wattmeter. The shunt circuit of thewattmeter is connected between the neutral and one of the outside wires. The current capacity, marked on the counter of the three-wire… … Fig. 27. Diagram of Connections of Westinghouse Three-Wire, Single-Phase Integrating Wattmeter. The total current capacity of a three-wire wattmeter is, therefore, twicethat marked on the counter, which represents the capacity of one side only. The counter records, hoAvever, the total energy…
