Title: Weighted calculation method for calculating wire size
Inventor: IWAMOTO MASATOSHI
IPC: H02G1/00
Filed: 2001-10-18
Abstract: PROBLEM TO BE SOLVED: To provide, inexpensively, safely, and simply, wiring that is rational and efficient. SOLUTION: The conventional calculating method wherein the voltage drop e is proportional to the distance L is changed to a realistic calculating method wherein the voltage drop e is proportional to the product of the current I and the distance L. The calculation is in accordance with interior wiring regulations and does not conflict with any standard or regulation. Depending on the situation, selection of the wire after a single calculation, or making adjustments for the purpose of reducing copper loss may be considered. Generally, the non- adjusting case is suited for a load circuit, and the adjusting case for a trunk circuit; however, when in doubt, clarifying the purpose will provide a guideline for the decision.  A loop circuit may continue to be safely used if a rupture occurs in one spot by merely removing the connection at the ruptured spot and has the effect of recovering the deficit of increased copper loss. This is effective in circuits with fluctuating load, plants having frequent layout changes, and is a new wiring method with small circuit loss, stable voltage, decreased failures, as well as reduction in maintenance cost.
