What is extra high voltage?
What is Extra High Voltage: The extra-high voltages will be added as per the consumer requirement. Typically, the voltage level between the 220kV to 760 kV is called Extra High voltages. Example for 400 kV: Dehar – Panipat Line. Example for 760kV: Anpara – Unnao. Ultra-High voltage:
Extra-high voltage refers to levels above 100,000 volts (100 kV) and up to 300,000 volts (300 kV) for AC systems and between 100,000 volts (100 kV) and 800,000 volts (800 kV) for DC systems. EHV systems are primarily used for long-distance power transmission, where higher levels reduce energy losses even further.
The definition of extra-high voltage (EHV) again depends on context. In electric power transmission engineering, EHV is classified as voltages in the range of 345,000– 765,000 V. [6] In electronics systems, a power supply that provides greater than 275,000 volts is called an EHV Power Supply , and is often used in experiments in physics.
Generally, EHV and HV (High Voltage; 60 kV ≤ V < 150 kV, EHV: Extra High Voltage; V ≥ 150 kV) is used for energy transmission to decrease the current in the line, what allows the reduction of the cross section of conductors and losses by Joule effect ( Joule law: W = RxI 2 xt = UxIxt, where “ t ” is the time ).
Feb 10, 2024 · High Voltage (HV) and Extra High Voltage (EHV) are two terms used in the electrical industry to describe the voltage level of electrical systems. While both HV and EHV systems operate at...
Sep 5, 2023 · Extra-High Voltage (EHV) and Ultra-High Voltage (UHV) Cable: are designed for long-distance and accommodating exceptionally high capacities. EHV cables can carry electrical currents above 230 kilovolts (kV), while UHV cables are designed to handle currents surpassing 800 kV.
EHV: Extra High Voltage (V ≥ 170 kV). HV: High Voltage (72,5 ≤ V ≤ 123 kV). The referred values of V are the highest voltage for equipments, according to IEC Standard 60038– IEC standard voltages. MV: Medium Voltage (3,6 kV ≤ V ≤ 52 kV). LV: Low Voltage (V ≤ 1 kV AC).
