The calculator computes the voltage drop across a conductor run for single-phase and three-phase AC circuits. It uses the exact phasor method, which is more accurate than the simplified approximation formula commonly used in basic tools. The key result — the scalar voltage drop — is computed as the difference in magnitudes between the source voltage and the load voltage, accounting for both the resistive and reactive components of the conductor impedance at the actual power factor angle.
Interactive tool designed as an educational resource to explore how conductor sizing and overcurrent protective device selection may be affected by different installation parameters. By adjusting inputs, users can better understand the relationship between conductor characteristics, load conditions, temperature ratings, correction factors, adjustment factors, and OCPD protection. The results are intended to support learning, discussion, and preliminary evaluation only.
Interactive tool designed as an educational resource to explore how fault currents are calculated. The user of the tool can quickly and easily create a simple online diagram and calculate fault currents and see the math behind the work. This is a great tool for those who want to learn more about what is going on behind the scenes.
This is a draft version of a tool for selecting the primary and secondary OCPDs and conductors for a transformer. I need your feedback and comments. let’s make this tool something we can use in our industry as a great educational resource.
This fault current calculator is a quick an easy way to estimate the maximum available fault current at a location in the power system. It will even create a label to meet the requirements of NEC Section 110.24.
This is a work in progress. My goal is to have a resource that provides information regarding history and changes for each section of the NEC. Please feel free to check this sight out and comment on any of this LIVING Code Book
This resource is perfect for those who want an indepth knowledge of how to properly select overcurrent protection. This is a must have for your power systems engineering library..
