Electrical wire calculator

Helps determine the proper wire size for an electrical circuit based on the voltage drop and current carrying capacity of an electrical circuit. Calculate Your Voltage Drop Determines wire size to meet specific voltage drop limits or calculates voltage drop for a specific conductor run. When sizing conductors, calculations limits wire size to voltage drop and NEC ampacity. Southwire's Re3TM Voltage Drop Calculator is designed for applications using AWG and KCMIL sizes only. How to calculate voltage drop, you ask? Download our mobile apps or enter your values in the web calculator below!

Enter the height, diameter and permittivity to calculate the ImpedanceNote: The unit of Height and Diameter should be the same.HeightDiameterElectrical Permittivity Formula for Wire over Ground Impedance CalculatorWhat is the wire over Ground Impedance Calculator? This online wire over ground impedance calculator is used to calculate the characteristic impedance (Zo) of wire over ground geometry by entering the wire diameter(d), wire height (H) from the ground, and relative dielectric constant εR (= 1 for air).What is wire over ground geometry?The transmission line is a conductor (wire) or conductors (wires) designed to carry electricity or an electrical signal over a large distance with minimum loss and less distortion. The transmission lines take many forms to accommodate a particular application's needs. The wire over ground is the one of the transmission line geometry where one wire/conductor having a diameter (d) is positioned at a height (H) from the ground. This transmission structure is used in rural electrification.The formula calculating the characteristic impedance of the wire over ground structure transmission is given below. Where,H - Height of the wire/conductor above the groundd - Diameter of the wire/conductorεR - Relative dielectric constant (1 for air).
