Description

Elspec G4420 Fixed Power Quality Analyser

The Elspec BlackBox G4420, the best power quality analyser series in the market today, is equipped with the revolutionary PQZIP patent algorithm for continuous waveform recording. This advanced analyser enables you to predict, prevent and troubleshoot an incidence easily, without the need to set any trigger or threshold in order to capture a specific event.

PQZIP inside

• Continuous waveform recording
• Trigger free setup
• 5,000 power parameters @ 1/2 cycle resolution
• Easy deployment

Class A

Far surpassing the highest standards set by the industry, the BLACKBOX device series complies with standards for: aggregations, time clock uncertainty, flagging, and transient influence quantities.

Superior Accuracy

Elspec’s pioneering measurement method utilizes a dual-range gain of 2 x 16 Bit to yield, a superior accuracy far surpassing IEC 61000-4-30 Class A requirements, thereby capturing the finest details & deviations in Power Quality parameters.

Synchronized Monitoring

A unique time synchronization algorithm assures that logged data from multiple units is synchronized & displayed on the same time scale with typical 0.1ms resolution. Every event on a grid is accurately analysed for precise root cause analysis, behaviour propagation, and traced to its source.

Applications

Utilities (Transmission, Distribution, Generation)

• Optimizes protective equipment configuration and substation automation solutions
• Ensures a reliable and consistent supply of energy
• Evaluates the performance of breakers and relays
• Identifies and manage peak demand
• Real time power quality monitoring to meet any international standard
• Produces detailed & comprehensive statistical records

Energy Consumer (Critical Power, Industrial, Commercial, Etc)

• Measures and analyses system efficiency, provides solutions and increases profits
• Negotiates capabilities with power providers
• Detects electric bill inconsistencies
• Avoids power quality compliance issues
• Monitors and analyses power quality in real time

Continuous Waveform Recordings

The G4420 portable power quality analyser is able to record and store all electrical waveform continuously for more than a year, with no gaps in the data. The G4420 portable power quality analyser offers a clear and comprehensive picture of the conditions before, during, and after an event.

Supreme Trends Resolution

The G4420 portable power quality meter measures and records 5,000 power parameters continuously at a resolution of ½ cycles, 10/12 cycles, 150/180 cycles, 10 min and 2 hours of which, any given resolution is calculated for display and reporting purposes. Hence, there is no need to select which parameters to log, and more importantly, which parameters to ignore.

Harmonics & Inter-Harmonics Analysis

The G4420 portable power quality analyser has two FFT engines for harmonics analysis: Cycle by Cycle: performs FFT at 1 cycle resolution for extended bandwidth. This engine provides 512 harmonics order at 50Hz resolution. 10/12 Cycles: performs FFT 10/12 cycles resolution for extended resolution and sub-grouping calculation. This engine provides the magnitude and angle of 512 spectrum components at 5Hz resolution.

Comprehensive Event Mechanism

The G4420 portable power quality analyser is designed to detect any event occurring on your system. The mechanism allows you 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 rate of changed limits. The G4420 analyser is capable of recording waveform signals continuously. The event configuration doesn’t trigger the recording but rather stores summary logs including start and end time, duration, severity and magnitude of the event. All events can be displayed in a tabular or scatter charts as CBEME/ITIC.

The Elspec G4420 Blackbox is an approved product on the Energy Technology List.
