Real Voltage Drop (Series)
10 - 50 downloadsAdd this app to your lists
The series calculator calculates the total voltage drop at the most distant connected load from the voltage source, lists the accumulated load at each segment, the voltage drop for each segment and the accumulated voltage drop at each segment.
The app also includes a standard single point voltage drop calculator that solves for conductor gauge, voltage drop, maximum length and maximum load.
Both modules can output the results in an email.
The calculators implement the method given in ANSI/IEEE Standard 141, 1993 - "Calculation of Voltage Drops" and use the formula for exact voltage drop. Many other calculators use an approximate method. The AC resistance and reactance values are from NEC Ch. 9, table 9 and the DC resistance values are from Ch. 9, table 8.
The app includes help files with explanatory text on how to correctly perform the series voltage drop calculation.

1.1 - Fixed a bug in the single module which would cause the voltage drop to sometimes display incorrectly when the load was set to kVA.
