Q: What are the two power distribution equipment?: Such as generator, transformer, circuit breaker, isolating switch, bus, power cable and transmission lines, etc..

Q: AC distribution equipment including distribution box: protection of the power supply system is between the power supply and the load are connected, disconnected, conversion

Q: DC transmission equipment: Power supply operation of power plant and substation in nowadays are used in DC power supply, it provides power for the control of the load and power load and DC emergency lighting load, is the foundation of modern electric power system control and protection

Q: Transmission system and distribution system: Distribution system is the power supply to the distribution load for the purpose of the general voltage level of not more than 10KV

Q: What is the difference between power supply and distribution: The problem is you estimate from the injection test out the electric power, is the power system of power plant and the national grid is responsible for part of the design, the design of power plant and power lines, its design must be designed by a qualified electric power design institute

Q: What is the role of transmission system and distribution system in power grid: Such as water resources are concentrated in the river basin water level drop larger place, fuel resources in coal, oil, gas.

Q: Are electric wires and cables belong to distribution equipment?: Wire rod products for the transmission of electric (magnetic) energy, information and electromagnetic energy conversion.

Q: Transmission lines are not electrical equipment?: Transmission lines are not electrical equipment? The answer is: the device is a function of the assembly

Q: Transmission and transformation equipment: Power transmission and transformation of the protection of the main transformer, relay protection devices, lightning arrester, etc..
