Q:What is the difference between power supply and distribution
Power supply and distribution is part of the use of general by the Architectural Design Institute of electrical professional
Q:Transmission lines are not electrical equipment?
If you are satisfied, please accept it as a satisfactory answer
Q:What is the role of transmission system and distribution system in power grid
power plant and the load center often separated by long distances, resulting in the problem of power transmission. The power is sent to the user only hydropower area can be fully utilized by high voltage transmission line
Q:Are electric wires and cables belong to distribution equipment?
Wire and cable for the transmission of electric (magnetic) energy, information and realize electromagnetic energy conversion of wire products, wire and cable general also referred to as the cable,
Q:Transmission and transformation equipment
Transmission and transformation of basic electrical equipment, including the main wire, transformers, switchgear, high voltage insulators, etc.
Q:An introduction to the interpretation of flexible AC transmission systems
The series compensation device such as thyristor controlled series capacitor (TCSC), thyristor controlled reactor (TCSR), static synchronous series compensator (SSSC), active power flow is mainly used to change the system of distribution, improve the system transmission capacity and transient stability etc.;
Q:Difference between distribution voltage and supply voltage
In general, the city substation will be reduced to 10KV 110KV to the electrical terminal.
Q:DC transmission equipment
Simply put, DC screen is to provide stable DC power supply equipment.
Q:What are the general requirements for working on distribution equipment?
When the high voltage line is not cut off, the person in charge of the work shall explain to the whole staff that there is electricity on the line and strengthen the monitoring
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
