Digital Network Analyzer (DNA)
The Doble F6880 Digital Network Analyzer (DNA) reveals details that are essential to helping protection engineers and relay test technicians quickly resolve issues in IEC 61850 network traffic.
This compact and lightweight instrument is paired with powerful software that analyzes IED communications and provides diagnostic and analytical functionality in real time.
The DNA is a digital substation multimeter, capable of plotting IEC 61850 sampled values (SV) and GOOSE messages via real-time oscillography, phasor, and tabular data views.
It is also a system event recorder, capturing events via customizable triggers and producing analysis reports that allow the user to evaluate network performance and power system anomalies, like voltage sag, harmonic distortion, and underfrequency.
The F6880 compares SV and GOOSE information from SCL files with the present network traffic to identify system misconfiguration issues such as missing, duplicated, or unknown messages.
The DNA can even be left connected in the substation for extended periods, offering remote access and control.
Assign ports to process bus, station bus and control networks and save along with other setup configurations for sharing and future plug-and-play efficiency.
Import SCL files to find baseline IED parameters. Create up to 3 networks to filter SV and GOOSE from Process/Station buses. Synchronize with PTP grandmaster clocks to achieve sub-microsecond network time synchronization.
Select individual GOOSE and SV control blocks to analyze and display. The DNA filters out all other streams at line-speed and can sample and display 16 sampled values streams simultaneously.
Create custom event trigger configurations that combine any number of Boolean logic gates with comparators that measure SV quantities and data attribute values in GOOSE packets. Capture all network information for a set duration.
Observe network traffic and apply deep mathematical analysis of analog quantities and network performance. Quickly navigate to lists that isolate the information. See instances of corrupted GOOSE and SV streams.
Save work in sharable .dna project files. Export events in PCAP and/or COMTRADE for sharing with other network/power-analysis tools. DNAs maintain security with encrypted PC communications, deny-by-default on all ports, and checksum validations on updates.
