Application and brief description

NET VISION 2010 is a portable device designed for a quick and precise measurement of the electric values of a three-phase network. It is used by power engineers for check of AC motors, relay current protections, electricity meters, etc.

The true RMS values of the three-phases of voltage and one current are measured simultaneously. Active power, reactive power, power factor, sequence of rotation, frequency, phase angle between two voltages, phase angle between voltage and current, peak values, crest factor are computed and indicated.

There are also other modes in which the device can draw the vector diagram, two waveforms in real time or indicate harmonic analysis. The current is measured with a current clamp to 100 A (or to 1000A by a special order).

The values and the waveforms are indicated on a graphic LCD display.

The device can work without batteries – it is supplied from the measuring circuit of the voltages.


Mode – “Indication of the measured values”

Indication of the measured values

The sequence of rotation and the frequency of the net are displayed permanently in this mode. Five more parameters are also displayed, which could be changed by the operator.

The following parameters could be displayed:

  • True RMS values of voltage and current (three voltages and one current)
  • Active power (each phase)
  • Reactive power (each phase)
  • Power factor (each phase)
  • Dephasing between voltage and current in [ Degree ]
  • Dephasing between two voltages in [ Degree ]
  • Peak values of voltage and current
  • Crest factor (Umax /(Uef * 1.41))

Mode – “Two beam oscilloscope”

Two beam oscilloscope

Two waveforms in real time are drawn on the graphic display in this mode. The operator can choose the waveforms from the three voltages and one current.

Mode – “Vector diagram”

Vector diagram

The three voltages and the current are drawn as a vector diagram in this mode.

Mode – “Harmonic analysis”

Harmonic analysis

Indication of the harmonics to 15th of one signal in real time.

Option – RS 232

The values in each mode are changed in every two seconds
