Electrical grid - Wikipedia electrical grid, electric grid or power grid, is an interconnected network for delivering electricity from producers to consumers. It consists of: generating stations that produce electric power; electrical substations for stepping electrical voltage up for transmission, or down for distribution; high voltage transmission lines that carry power from distant sources to demand-centers
Ensuring efficient flow of bulk energy· PDF fileThe HVDC converter transformers play a vital role within the HVDC systems; hence there are high requirements on their reliability and availability. Siemens Transformers have more than 100 years of experi-ence in manufacturing transformers – and were the first manufacturer worldwide to master the 800-kV level in 2008 for a Chinese customer.

Electrical substation - Wikipedia substation is a part of an electrical generation, transmission, and distribution system. Substations transform voltage from high to low, or the reverse, or perform any of several other important functions. Between the generating station and consumer, electric power may flow through several substations at different voltage levels.
