In electric power transmission engineering this refers to equipment designed for more than 345,000 volts between conductors. In electronics systems, a power supply that provides greater than 275,000 volts is known as an "EHV Power Supply". Experimental high-phase-order transmission lines have been built with up to 12 phases. These allow application of Extra High Voltage (EHV) design rules at lower voltages, and would permit increased power transfer in the same transmission line corridor width.The operating constraints involved in power transmission of long AC cable links is described.The 380 and 230 kV transmission lines designs are selected and studied and and suggests new data for the EHV lines. Low-level harmful effects of electrical lines could be missed, but they might be important for the population as a whole since electric lines are everywhere. Interest in potential health effects has focused
on the AC fields, and on magnetic fields in particular.
