A comprehensive energy management and power monitoring program is the key to success for any energy provider/consumer, regardless of their size. The Elspec BlackBox G4400 series is equipped with the PQZIP patent algorithm for continuous waveform recording. It enables the user to predict, prevent, and troubleshoot an incidence easily, without the need to set any trigger or threshold in order to capture specific events.

The PQZIP allows the G4400 Series to continuously record and store all electrical waveforms for extended periods with no gaps in the data. The Elspec measurement method uses a dual-range gain of 2 X 16-bit ADC yield, for superior accuracy, far surpassing IEC61000-4-30 Class A requirements. The G4400 Series features a threshold-free setup and is equipped with standard industrial protocols (Modbus TCP/IP and RTU; DNP 3; OPC) for seamless integration into any SCADA system. It provides PQ parameters according to EN50160, IEC61000-4-30/15/7, and other national standards, and the data may be analyzed over any network at any remote location.

The G4400 power quality analyzer measures and records 5,000 power parameters continuously at a resolution of 1/2 cycles, 10/12 cycles, 150/180 cycles, 10 min, and 2 hours of which, any given resolution is calculated for display and reporting purposes.

The G4400 Series 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 Series meter acts as an SNTP server, each meter on the network is synchronized to each other over LAN, allowing for accurate time stamping, without the need of a GPS.

The BlackBox has two FFT engines for harmonics analysis:

• Cycle by Cycle: Performs FFT at 1 cycle resolution for extended bandwidth; Engine provides 512 harmonics order at 50Hz resolution
• 10/12 Cycles: Performs FFT 10/12 cycles resolution for extended resolution and sub-grouping calculation; Engine provides the magnitude and angle of 512 spectrum components at 5Hz resolution

The G4400 series is designed to detect any event occurring on a system. The event mechanism allows the user to configure events on any measured parameter (more than 1,000) and/or I/O ports. The event mechanism supports out-of-limit events as well as the rate of changed limits as the G4400 records the waveform signals continuously. The event configuration doesn’t trigger the recording but stores summary logs including start and end time, duration, severity, and magnitude of the event. All the events can be displayed in tabular or scatter charts as CBEME/ITIC.

The PQZIP Patent compression algorithm enables the meter to continuously store waveform signals over a long period of time, whether an event of interest was identified. This technology is unique to Elspec and ensures precise and accurate characterization of electrical system dynamics.

• Continuous waveform recording
• 5,000 power parameters @ 1/2 cycle resolution
• Supreme Trend Resolution

The G4400 Series offers the option to expand the meter capability by adding the multi I/O module in conjunction with all metering functionalities. The I/O module includes analog and digital I/O as well as a relay output to specifically work with your application.

The multi I/O module extends the meter capability in order to replace RTUs and PLCs for energy management and substation automation. With the G4400 series, you can monitor the reliability of system apparatus such as transformers, circuit breakers, and other critical equipment. The G4400 series supports up to (2) I/O modules using internal power along with:

• 8 fast digital input at 16 sample/sec
• 4 fast digital output at 16 sample/sec
• 4 analog 4-20mA input sampled at 1Hz with programmable scaling
• 4 analog 4-20mA output
• 3 Relays
