The power is supplied to the system from the power station atAnderson at 15,000 volts over the Eastern division, and at 30,000volts over the Northern division. The power is received atsubstations suitably distributed along the lines, which containtransformers and rotary converters for reducing the pressure to600 volts and converting the power to direct current. Thegeneral plan of the distribution is shown in Fig. 46. THE MUNCIE-ANDERSON-INDIANAPOLIS DIVISION.
