Ваттметр цифровой ВТ-01-ТК
  • Three-phase network without neutral parameters continuous measurement.
  • Calculation of active, reactive and total power, power factor and network frequency by two wattmeters method.
  • Maximum values registration.
  • Measuring current and voltage transformers coefficients presetting.
  • Measuring results displaying according to transformation coefficients.
