5 Questions
What are some industrial applications of high voltage?
High voltage is used in electrical power distribution, cathode-ray tubes, generating X-rays and particle beams, producing electrical arcs, ignition, photomultiplier tubes, high-power amplifier vacuum tubes, as well as other industrial, military and scientific applications.
What is high voltage electricity?
High voltage electricity refers to electrical potential large enough to cause injury or damage.
How is high voltage defined numerically?
The numerical definition of high voltage depends on context, with international standards setting it at above 1000 V for alternating current, and at least 1500 V for direct current.
What are the safety considerations for high voltage equipment and conductors?
Equipment and conductors that carry high voltage warrant special safety requirements and procedures due to the possibility of causing a spark in air and the danger of electric shock by contact or proximity.
What voltage range does ANSI define as high voltage for 60 Hz electric power systems?
ANSI C84.1-2020 defines high voltage as 115 kV to 230 kV.
