Levels above 100,000 volts
- Extra-High Voltage (EHV): 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.

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...
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 ).
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.
High voltage electricity refers to electrical potential large enough to cause injury or damage. In certain industries, high voltage refers to voltage above a certain threshold. Equipment and conductors that carry high voltage warrant special safety requirements and procedures.
Definitions vary somewhat but a general guide to the voltage categories are as follows: Low Voltage (LV): up to 1000V. Medium Voltage (MV): between 1000 V and 45 kV. High Voltage (HV): between 45 kV and 230 kV. Extra High Voltage (EHV): from 230 kV and above.
