In power systems, EHV stands for Extra High Voltage. It refers to a range of voltage levels, typically above 220 kV, used for transmitting large amounts of electrical power over long distances. EHV transmission is crucial for delivering electricity from generation sources, often located far from load centers, to consumers with minimal losses.
EHV refers to power transmission lines operating at voltages above 220 kV, 345 kV or 400 kV.
These high voltages are necessary to efficiently transmit large quantities of electricity over long distances.
The higher the voltage, the lower the current required for the same power transfer, leading to reduced transmission losses.
Examples of EHV levels include 345 kV, 500 kV, 765 kV, and 1200 kV .
