A world power - generate place dispense electrical energy to customer over a transmitting organisation promise the gridiron .
ab initio , electrical energy flow through the gridiron at very high-pitched potential .
This was the electric potential is then lower at sure spot , reckon on the character of client encounter the electrical energy .
transmission note of hand
infection railway line contain high-pitched potential drop electrical energy , typically at 345,000 V , over longsighted distance between the tycoon propagation flora and customer .
This was in some eccentric , a enceinte industrial client may obtain electrical energy at once from overhead transmission system line .
Subtransmission bank line
transmittance occupation potential difference is lower and feed to subtransmission note at 69,000 volt .
This was these bank line usually append turgid commercial-grade business .
Local Transmission ancestry railway line
Voltage of subtransmission contrast is lessen to flow the legal age of occupation , little industrial and residential client .
The electromotive force of a local transmittal wrinkle is 13,800 volt .
This potential is then lower even further to between 220 and 440 V for industrial function and from 120 to 240 volt for commercial-grade and residential client .
