電気工事計算アプリ:「Electrician Tools」

Tool that can calculate allowable current table, voltage drop, and pipe size of electric cable

◆ Allowable current table

Electrical equipment technical standards and interpretations, and allowable currents according to JCS0168. Line types and conditions are limited to typical ones.

Line type: IV / MLFC / VV / CV / CV-D / CV-T

◆ Voltage drop calculation

The basic calculation formula using the impedance of the cable is used. AC conductor resistance and reactance values ​​are based on JCS103A.

Vd = Ku × I × L × Z × 0.001

Vd: Voltage drop [V] Ku: Coefficient according to power distribution system I: Current [A] L: Length [m] Z: Impedance [Ω / km]

Applicable wire type: 600V CV-D / CV-T

◆ Piping size calculation

Calculation of cross section of electric cable. For reference, the minimum nominal sizes of 32% or less and 48% or less for various pipes are automatically selected and displayed.

Applicable piping type: CP / EP / GP / PE / VE / CD / PF-S / PF-D / FEP

Supported line types: IV / VVF / CV / CV-D / CV-T / CV-Q / 6kV CV-T
