Power Network Analyser
The N100 meter is a programmable digital instrument designed for the measurement of 3-phase, 3 and 4-wire power network parameters in balanced or unbalanced systems. The measured values are displayed on a two-color LED display. The meter enables control and optimization of the power electronic devices, systems and industrial installations. The meter provides measurement of: RMS of voltage and current, active, reactive and apparent power, active, reactive and apparent energy, power factors, frequency, the harmonics of current and voltage /up to 51st/, THD of voltage and current, averaged active and apparent power P Demand, S Demand, averaged current I Demand /15, 30 or 60 minutes/. Voltages and currents are multiplied by given voltage and current ratios of the measuring transformers. Power and energy indications take into account all programmed ratio values. The value of each measured value can be transmitted to the master system via the RS-485 or Ethernet interface. Three relay outputs signal the overflow of the chosen value, and the pulse output can be used for the consumption check of 3-phase active energy. The programmable analog outputs map the assigned parameter. The pulse input can be used to check the counters with the pulse outputs.
There is a galvanic separation between following units of the meter:
–– supply
–– voltage inputs
–– current inputs
–– RS485 interface
–– Ethernet interface
–– pulse input
–– pulse output OC
–– alarm outputs
–– analog outputs
Rail Mounted Power Network Meter
The N43 meter,assembled on a rail, is a programmable digital instrument designed for the measurement of 3-phase, 3 or 4-wire power network parameters in balanced or unbalanced systems. The measured values are displayed on a dedicated LCD display. The meter enables control and optimization of the power electronic devices, systems and industrial installations. The meter can be used for measuring: RMS of voltage and current, active, reactive and apparent power, active and reactive energy, power factors, frequency,THD and averaged values P Demand – “power guard”, S Demand, I Demand /15, 30 or 60 minutes/. Voltages and currents are multiplied by given voltage and current ratios of the measuring transformers /for indirect
connections/. Power and energy indications take into account all programmed ratio values. The value of each measured value can be transmitted to the master system via the RS-485 interface. Three relay outputs signal the overfl ow of the chosen quantity, and the pulse output can be used for the consumption check of 3-phase active energy.

Three Phase Power Network Meter
The N14 meter is a programmable digital panel instrument destined for the measurement of 3-phase, 3 or 4-wire power network parameters, in balanced or unbalanced systems with the simultaneous display of measured quantities and digital transmission of their values. This network parameter meter enables the control and optimization of power electronic devices, systems and industrial installations. The N14 meter ensures the measurement of: RMS voltage and current, active, reactive and apparent power, active and reactive energy, power factors, frequency, mean active power (e.g. 15-min mean power). Voltages and currents are multiplied by given current and voltage ratios of measuring transformers. Indications of power and energy take into consideration programmed ratio values. The value of each measured quantity can be transmitted to the master system through the RS-485 interface. The relay output signals the exceeding of the chosen quantity and the impulse output can be used for the consumption control of the 3-phase active energy. The meter has a detection and signaling of incorrect phase sequence. The meter is fixed to the panel by means of screw holders.
