Of course, this idea existed only in theory.
According to the data Avita had submitted, adding a sturdy protective casing to the Magic Array Lines had greatly improved the stability of magic power transmission, but the process was still not truly lossless. At present, the limit was five hundred meters, beyond which the magic power could no longer retain its basic functionality and meet a magic array's minimum requirements.
Past five hundred meters, losses within the Magic Array Lines would still disrupt the magic power, making it impossible to activate a magic array successfully.
Although this was a full fivefold increase over the previous limit of one hundred meters, the gap was still too vast to compare with electrical wires, which could carry electricity over a thousand kilometers away.
But as Xu Yi thought it over, a question occurred to him.
On Earth, laying a power grid to a destination allowed electricity to be delivered there, but in reality, electricity suffered losses whenever it traveled through any conductor.
Power plants on Earth could transmit electricity hundreds, thousands, or even several thousand kilometers mainly because power grids consisted of more than just wires. Substations, distribution rooms, and other regulating facilities were installed at intervals to ensure that the electricity maintained sufficient strength after traveling each stretch, meeting actual usage requirements.
Another reason was that a power plant's output voltage was generally far higher than the voltage needed by users. Even with losses along the way, there was still enough room for adjustment when the electricity reached a substation.
Applying this setup to magic power transmission would mean having the Magic Crystal supplying the power provide high-intensity magic power, then using some facility along the way to regulate its frequency. The incoming magic power would be adjusted again to meet the intensity
