1 APPLICATION
ND30PNET meter is a digital programmable instrument designed to measure network
parameters of single-phase 2-wire and three-phase 3 and 4-wire balanced and unbalanced
systems. The measured values are displayed on a color graphic screen TFT 3.5” with a
resolution of 320 x 240 pixels. The meter enables the control and optimization of power
electronic devices, systems and industrial installations.
It provides measurement of: RMS voltage and current, active, reactive and apparent power,
active, reactive and apparent energy, power factor, frequency, harmonic currents and voltages
/up to 51st/, THD of current and voltage, average active and apparent power, P Demand,
S Demand, averaged current
I Demand /15, 30 or 60 minutes/. Voltages and currents are multiplied by given current and
voltage transformer ratios of measuring transformers. Indications of power and energy include
the values of programmed ratios. The values of the measured quantities can be transmitted to
the host system through RS485 interface or Ethernet / Profinet interface, relay outputs signal
overruns of the selected parameters, programmable analog output maps the assigned
parameter. Temperature inputs can be used to control the temperature of the windings of
transformers, motors.
The meter has a galvanic separation between the individual blocks of:
- power supply,
- voltage inputs,
- current inputs,
- RS485 Interface,
- Ethernet/Profinet interface,
- alarm outputs,
- analog output,
- Pt100 sensor input.
