Definition

Noun: - A unit of electrical potential equal to one thousand volts: "kV" is an abbreviation for "kilovolt," a standard unit of measurement in electricity and physics representing 1,000 volts.

Usage
  • The term "kV" is used primarily in technical, scientific, and engineering contexts to quantify high electrical voltages.
  • It functions as a noun, often appearing in written specifications, diagrams, and reports. It is typically read aloud as "kilovolt(s)."
Examples
  • Noun:
    • The transmission line operates at 500 kV. (The transmission line operates at 500 kilovolts.)
    • A safety clearance is required for equipment above 1 kV. (A safety clearance is required for equipment above 1 kilovolt.)
    • The transformer steps up the voltage to 230 kV. (The transformer steps up the voltage to 230 kilovolts.)
Advanced Usage
  • "kV" as a modifier: While "kV" itself is a noun, it is frequently used attributively (like an adjective) before other nouns to specify the voltage rating.
    • We need a 33 kV cable for this project. (We need a 33-kilovolt cable for this project.)
    • The kV rating of the insulator is critical. (The kilovolt rating of the insulator is critical.)
Variants and Related Words
  • Kilovolt (n): The full, unabbreviated form of "kV."
  • V (n): Abbreviation for "volt," the base unit. One kV equals 1,000 V.
  • MV (n): Abbreviation for "megavolt," a unit equal to one million volts or one thousand kilovolts (kV).
Synonyms
  • Kilovolt: The full term is a direct synonym.
  • Thousand volts: A descriptive phrase with the same meaning.
Notes on Usage
  • Capitalization: The abbreviation is most correctly written in lowercase ("kV"), though "KV" is sometimes seen in informal contexts. The "k" stands for "kilo-" (thousand).
  • Context: This term is highly specialized. It is not used in everyday conversation but is common in fields like electrical engineering, power distribution, and physics.
  • Plural: The plural can be written as "kVs" or, more commonly, the same form "kV" is used for both singular and plural (e.g., 1 kV, 500 kV). When read aloud, the plural "s" in "kilovolts" is pronounced.
Noun
  1. a unit of potential equal to a thousand volts
