How is it possible that there''s not a complete circuit to the …

Thus, in AC circuits there doesn''t need to be a complete circuit. Since voltage is relative, what happens if the voltage-wave from the power plant is always below (or above) 0-volts/ground? It''s true that this will cause current to flow in only one direction, but only for a moment; as electrons flow out of the power line and into the earth, the voltage around that point of earth drops.

Generator circuit breakers bring advantages to power plant …

Generator circuit breakers are power plant devices located between the generator (which produces electricity at a voltage of around 15-25 kV) and the step-up transformer (which increases this voltage up to the grid transmission voltage – 200 kV to 800 kV). They play a key role in the protection of the transformer and the generator in case of fault ...
