A comprehensive energy management and power monitoring program is the key to success for any energy provider/consumer, regardless their size. The G4420, the most advanced power meter in the market today, is equipped with the revolutionary PQZIP patent algorithm for continuous waveform recording. It enables you to predict, prevent and troubleshoot an incidence easily, without the need to set any trigger or threshold in order to capture specific event.

High End Power Quality and billing measurement
Thousands of power quality and energy usage parameters are available in real time in the G4420. The G4420 provides advanced power disturbance recordings
meeting the highest standards on the market. The meter is designed with the most accurate level in order to be used as a primary meter, a sub-meter, as a detector of inconsistencies in electricity bills.
Harmonics Recording
The BLACKBOX is equipped with two FFT engines for harmonics analysis:
- Cycle by Cycle: performs FFT at 1 cycle resolution for extended bandwidth. This engine provides 256 harmonics component at 50/60Hz resolution.
- 10/12 Cycles: performs FFT at 10/12 cycles resolution for an extended resolution and a sub-grouping calculation. This engine provides the amplitude and angle of 512 harmonic components at a 5Hz resolution.
Accuracy standards
The G4420 superior accuracy surpasses by far, the highest standards set by the industry. The G4420 compiles with standard for:
- Power Quality
- IEC 61000-4-30 Class A
- IEC 61000-4-15 Flicker meter
- IEC 61000-4-7 Harmonics and inter-harmonics
- Energy
- ANSI C12.20 0.2%
- IEC 62053-22/23 class 0.2
SCADA Compatible
The G4420 series is equipped with standard industrial protocol for seamless integration into any existing SCADA system:
- Modbus TCP/IP and RTU
- DNP 3
- OPC
Time Synchronization
The G4420 uses a special continuous synchronization algorithm to ensure accurate time stamping of up to 1μsec using SNTP, GPS, IRIG-B and DCF-77. Each G4400 meter acts as a SNTP server therefore each meter on the network is synchronized to each other over LAN. This allows accurate time stamping, without the need of a GPS.
