Product Description

An AC Voltmeter (Three Phase) is a device used to measure the voltage in a three-phase AC (Alternating Current) system. In a three-phase system, the AC voltage fluctuates in three separate phases, typically spaced 120 degrees apart, and the voltmeter is designed to measure the voltage in each of these phases.

FEATURES
  • Displays Line to Line Voltage, Line to Neutral Voltage, Average voltages and system frequency.
  • Password Protected.
  • True RMS measurement of parameters.
  • Auto/Manual scrolling of parameters
  • Easy Programming with push buttons on front facia.
  • RS-485 Communication optional.
  • Relay Output for alarm can be provided.(optional)

FAQ

  • 1. What is a Three-Phase AC Voltmeter?

    A Three-Phase AC Voltmeter is a device used to measure the voltage in a three-phase electrical system. It measures both the individual phase voltages and the line-to-line voltages in a three-phase alternating current (AC) setup.

  • 2. What is the difference between phase voltage and line voltage?

    • Phase Voltage: The voltage measured between any one phase (e.g., R, Y, or B) and neutral.
    • Line Voltage: The voltage measured between any two phases in the system (e.g., between R and Y).

    In a three-phase system, line voltage is √3 (approximately 1.732) times the phase voltage.

  • 3. What voltage range can a Three-Phase AC Voltmeter measure?

    The voltage range of a three-phase AC voltmeter can vary depending on the model, but it generally measures from low voltages (such as 110V or 230V) up to high voltages used in industrial settings (up to several kilovolts).
