Main characteristics:
- TRMS analysis on single phase, three-phase systems with 3 or 4 wires, balanced and unbalanced;
- Voltage measurement on each half-cycle (10ms);
- Network parameters (voltage, current, active power, inductive power, capacitive power, apparent power, power factor, etc…);
- Analysis of the voltage and current harmonic components (CEI EN 61000-4-7) up to the 50° order (QNA412);
- Network disturbances provided by CEI EN 50160 as required by CEI EN 61000-4-30 class A: voltage swells, gaps and network interruptions, variations in width and frequency, unbalance among the phases (QNA412);
- Flicker measurement (CEI EN 61000-4-15) (QNA412);
- Measurement of neutral current and neutral-ground voltage (QNA412-QNA413);
- High immunity to electromagnetic disturbances, atmospheric discharges and transitory phenomena;
- Auto range function, which guarantees a high measurement accuracy on every voltage and current range;
- Internal memory for the memorization of the measured parameters (different according to the model);
- Internal rechargeable battery, which allows the data recording even in case of prolonged lack of power supply;
- Data communication through serial port RS232 and RS485 or through modem GSM/GPRS;
- Supplied software Power-Vision for the data transmission and analysis.
