Note: 1. 60 Hertz reactance in ohms per mile of each conductor of a single phase, or of a three phase, symmetrical tri-
angular spacing. For other arrangements of conductors see below. The reactance for other frequencies is F/60
times the table values. Reactance values for copper wire are for concentric standard copper conductors. Reac-
tance values for aluminum cable conductors are approximately correct.
The Siemens Line Drop Calculator software application
simplifies the calculation of these parameters. Simply
enter the system values and the application automatically
calculates the resistive and reactive components for you.
Enter these values in the <REGULATOR> menu, and the
MJ-4 automatically compensates for the line drop when
adjusting the output voltage of the regulator.
Contact your Siemens representative about obtaining this
application. You may also download this application from
the Siemens web site (see Section 1.8). After arriving at
the website, select Products, and then the Voltage Reg-
ulator item. This application is available on the Download
page.
