Please write the word or phrase that fits the blanks!!!!!!!!!!!!!

1. Electricity generated at power plants is normally stepped up to kV (range of in the plants switchyard before it goes out onto transmission lines voltage by 2. At load centers, near where the electric power will be usedm at kV (range of voltage) for distribution to local substations reduce the voltage to users 3. The function of the turbine at a power plant is to turn the which converts energy to energy 4. Most generators at power plants are machines in which a magnetic field circuit mounted on the spins in the presence of stationary coils wrapped around the core ofthe 5. High-voltage transmission lines have specially designed insulators to guard against which is an electrical discharge between two conductors having a large potential difference between them 6. High-voltage transmission lines are made from miname of material) Instead of a single cable, the transmission line consists of a bundle of smaller strands that are often reinforced by a core made of on(name of material). Bundling of conductors is the most economical way to achieve the large effective diameter of line needed to guard against discharge, which damages conductors and causes electromagnetic interference 7. Circuit breakers at substations are immersed in a medium consisting of to protect against and which is a form of fire that can start when inductors discharge their energy to the source when the circuit is broken switches make it possible to isolate sections of a distribution circuit Unlike circuit 9. Surge arrestors protect substation equipment from breakers, which open a circuit when a problems arise, surge arrestors create a short circuit that routes current through the arrestor and down to 10. The frequency of an electric power system is proportional to the of the generator and the number of of the generators field circuit
