How To Calculate Voltage Drop
Voltage drop, also known as voltage loss, is the reduction in voltage that occurs as electricity flows through a conductor, such as a cable or wire. It is an important consideration in any electrical installation, as it can cause problems with the operation of equipment and devices that are powered by the cables and wires. In order to ensure that your electrical installation is safe and efficient, it is important to calculate the voltage drop and take steps to minimise it according to the Australian Standards AS/NZS 3000:2018 and AS/NZS 3008:2017.
There are several methods to calculate voltage drop, including the Ohm’s Law method, the Voltage Drop Formula method, and the Power Factor method.
The Ohm’s Law method involves using the formula: Voltage Drop = Current x Resistance, where Current is measured in Amps and Resistance is measured in Ohms.
The Voltage Drop Formula method involves using the formula: Voltage Drop = 2 x Current x Length x Resistance / 1000, where Current is measured in Amps, Length is measured in meters, and Resistance is measured in ohms per meter. It’s important to keep in mind that the allowable voltage drop varies depending on the application, and it’s essential to comply with the standards of AS/NZS 3000:2018 and AS/NZS 3008:2017.
CableHero uses the most accurate method to calculate the voltage drop which is the Power Factor method to calculate voltage drop and ensures compliance with the Australian standards of AS/NZS 3000:2018 and AS/NZS 3008:2017. Additionally, CableHero also provides a wide range of other tools to help with cable sizing and installation, including a cable size calculator, cable sizing calculator, wire size calculator, and solar cable size calculator.
When installing electrical cables and wires, it’s important to use the appropriate size of cables and wires to minimize the voltage drop and avoid any damage on the equipment, according to the standards of AS/NZS 3000:2018 and AS/NZS 3008:2017. With CableHero’s cable sizing calculator online, you can easily find the perfect size for your installation.
It’s also important to secure and protect the cables and wires properly when installing them, to use the appropriate materials for backfilling the trench, and to follow all local building codes and regulations.
In conclusion, voltage drop is an important consideration in any electrical installation, and it is important to calculate it and take steps to minimise it according to the Australian Standards AS/NZS 3000:2018 and AS/NZS 3008:2017. CableHero’s voltage drop calculator and other tools make this process easy and straightforward. Whether you’re a professional electrician or Engineer, CableHero’s cable size calculator online is a great resource to use to ensure that your electrical installation is done safely and efficiently.
