Q:Transmission system and distribution system: Simply put, you can distinguish between the end of the cable to the use of electrical equipment (motor, power box) is the distribution system to the substation, transformer is the transmission system

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

Q:What is the transmission line, what is the power distribution equipment: As the name implies, the transmission is by the power plant or power center regional power grid (sending end), to the load center power grid (by the end) of the transmission of electricity; power distribution is to be distributed by the substation or bus power down.

Q:What are the general requirements for working on distribution equipment?: Can be plugged into the elbow cable connector, not load operation.

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:Power distribution equipment should be prepared before the blackout?: after the high and low voltage power failure, the work must be carried out before the first inspection

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 are the two power distribution equipment?: The two equipment is the equipment for the control, protection, monitoring and measurement of the work of the primary equipment.

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:Main equipment of high voltage direct current transmission: Converter also known as converter valve is the key equipment in the converter station, its function is to achieve rectification and inverter
