Any voltage above 1000 volts
- According to the International Electrotechnical Commission (IEC), HV is typically defined as any voltage above 1000 volts for alternating current (AC) systems and 1500 volts for direct current (DC) systems. However, the term "HV" can also refer to voltages as low as 50 volts in some safety regulations, depending on the context.

As mentioned earlier, the IEC defines HV as 1000 volts for AC and 1500 volts for DC. However, some safety regulations might consider voltages as low as 50 or 600 volts as HV. HV is used in power transmission and distribution to transport electricity efficiently over long distances.
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.
High (HV), Extra- High (EHV) & Ultra-High Voltages (UHV) - 115,000 to 1,100,000 VAC. Medium Voltage (MV) - 2,400 to 69,000 VAC. Low Voltage (LV) - 240 to 600 VAC. Generac issued a white paper titled Medium Voltage On-Site Generation Overview. The white paper compares NEC to ANSI Standards.
Since then, technology improvements especially in the area of power electronics have enabled high voltage direct current (HVDC) applications. HVDC allows controlled transmission of large amounts of power efficiently over very long distances in narrower rights-of-way.
High voltage is simply a voltage above a given threshold. In the context of building wiring and the general use of an electrical apparatus, the International Electrotechnical Commission defines: high voltage as more than 1,000 volts (V) of alternating current (AC) and above 1,500 V of direct current (DC).
Nov 2, 2023 · What is high electrical voltage? "High electrical voltage" refers to voltages significantly higher than the voltage levels used in everyday applications. While precise definitions vary by regulations and location, high voltage generally falls in the range of 69 kV to 230 kV.
High voltage power lines are used for the transmission of electricity over long distances. [1] Electrical transmission is the process of delivering generated electricity - usually over long distances - to the distribution grid located in populated areas. [2] .
