Line to ground voltage formula
NettetFind the area enclosed by two line Voltage wave forms… the “lines” intersect each other at 5 Pi / 6 and 11 Pi / 6 so use these as your limits of integration. Now find the area enclosed by one line and neutral for an equal period of time (from 0 to Pi) The first calculation will give 4 Cos 30 the second one will give 2 http://www.electricalaxis.com/2024/10/example-line-to-line-fault-calculation.html

For instance, if a line-to-line fault occurs 50 feet from a transformer, then 100 feet of cable impedance must be included in the calculation. The calculations on the following pages illustrate 1Ø fault calculations on a single-phase transformer system. Both line-to-line and line-to-neutral faults are considered. Note in these examples: a.
NettetHistorically, the "conventional" volt, V 90, defined in 1987 by the 18th General Conference on Weights and Measures and in use from 1990 to 2024, was implemented using the Josephson effect for exact frequency-to-voltage conversion, combined with the caesium frequency standard.For the Josephson constant, K J = 2e/h (where e is the elementary … NettetEnter the phase voltage then press the calculate button to get the line voltage. Line voltage is V (L-L) in volts equal to root 3 times of the phase voltage V (L-N) in volts. Example: …
