Fig. 23. Connections for Single-Phase Circuit; Potential exceeding 500Volts. The illustration shows the method of connecting the meter to a single-phase circuit carrying current at a potential exceeding 500 volts. To keepthe high potential current out of the meter, hoth a series and a shunt… … Fig, 24. Connections for Polyphase Circuits ; Current not exceeding 100Amperes, Potential not exceeding 500 Volts. The illustration above shows the method of connecting two meters to athree-wire polyphase circuit, in which the current traversing each of the out-side wires does not exceed 100…
