For a given quantity of power transmitted, doubling the voltage will deliver the same power at only half the current. Since the power lost as heat in the wires is directly proportional to the square of the current, doubling the voltage reduces the line losses by a factor of 4. While power lost in transmission can also be reduced by increa…See more on en.wikipedia.orgPrinciple Of Vacuum Circuit Breaker – blog naturalremedynow/principle of vacuum circuit breaker2020/11/5Chapter two, to profile the prime makers of three Phase Vacuum Circuit Breaker, with price, sales, income and worldwide market share of three Phase Vacuum Circuit Breaker in 2017 and 2018.
