Printed at 10:01pm 21st June 2024## Line Losses Calculator## An automatic calculator to work out line losses in DC powered systemsIn our article (Minimising Line Losses in RE Systems1) we looked at how the diameter of wire (cable) should be selected to ensure that line losses (i.e. energy lost when the current flowing through a wire heat it up) are kept below 10%.If you are interested in understanding the equations which are used to make the calculations below, then we recommend you read the article linked to above. ## Wire Size CalculatorEnter the peak (volts DC - e.g. 14V to 20V for a 12V rated wind turbine), charging voltagewire length (metres), peak current (Amps), and maximum acceptable power loss (%, we suggest 10% or lower), and click Calculate to view the minimum cross sectional area of the wire you should use.To convert the above wire cross sectional area to AWG, mm diameter, or inch diameter, click here to go to our (Automated AWG Wire Size Converter2). Remember to choose a wire with a slightly larger cross sectional area than that recommended above to ensure that power losses are below your maximum acceptable percentage.## Line Losses CalculatorAlternatively use the calculator below to work out theline losses for a system with a given wire size (diameter measured in mm).## Web Link References(1) http://www.reuk.co.uk/Minimising-Line-Losses-in-RE-Systems.htm( 2) http://www.reuk.co.uk/AWG-to-Square-mm-Wire-Size-Converter.htmArticle from REUK.co.uk: http://www.reuk.co.uk/Line-Losses-Calculator.htmPublished: 24th September 2014 © REUK 2024 |
