Description

3-phase power network meter

• Measurement of power network parameters in 3 or 4-wire balanced or unbalanced systems
• Tetraquadrantic measurement of power and energy (P+, P-, QL, QC).
• Indications taking into consideration values of programmed ratios.
• Measurement of 15-minutes’ mean power.
• Digital transmission to the Master system through the RS-485 interface (MODBUS).
• Configurable alarm output and current and voltage ratios.
• Programmable parameters using push buttons or through the RS-485 interface using the free LPCon program.
• Impulse output of OC type for the retransmission of 3-phase active energy.
• Battery support of configuration data and state of watt -hour meters at supply decays.
• Detection and signaling of incorrect phase sequence.

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.
