Application Scope
The GOOSEMeter ONE is designed to assist engineers and technicians in commissioning and testing electrical power systems using the IEC-61850 standard. It ensures the correct broadcasting of GOOSE messages across IEDs in substations, identifying issues in IEDs, switching hardware, or interconnection cables. The device simplifies the interpretation of cryptic GOOSE messages by assigning 'electrical names' and using indicators, reducing interpretation errors. Its handheld design allows easy access in confined spaces, and it poses no risk of altering network configurations, unlike non-dedicated systems.

Description
The GOOSEMeter ONE functions as a general-purpose IEC-61850 GOOSE sniffer and dataset monitoring instrument. It bridges the gap between code data and electrical indicators, converting data into light indicators and status changes. The device can store tests and templates, which can be downloaded and analyzed on a computer using GOOSESync software. It features a user-friendly interface with a TFT display, touch panel, and Windows CE operating system. The device is compact and lightweight, with ergonomic design features for handheld use.

IEC 61850 'Multimeter'
The GOOSEMeter connects to the IEC 61850 substation bus or directly to a relay's Ethernet port. Users can select datasets, follow GOOSE messages, check statuses, view histories, and create templates. The device requires no configuration, is read-only, and is not PC-dependent, making it suitable for field testing, commissioning, troubleshooting, laboratory work, and IED development.

Functional Description
The initial window detects and displays all published datasets in the IEC-61850 network, with color-coded LED indicators for message status. The GOOSE messages explorer provides detailed information on the last GOOSE message, including event time, sequence number, state, and data. Users can filter data, edit names, and save templates for future use. The history panel records changes in GOOSE messages for analysis.

Supplied Accessories
The GOOSEMeter ONE comes with a transport bag, Ethernet and USB cables, a stylus pen, a power supply adapter, an instruction manual, warranty and registration instructions, and a CD with GOOSESync software.

Characteristics
The device offers plug-and-run functionality, in-service testing, USB storage, and real-time monitoring of GOOSE messages. It features a high-definition touch screen, template editor, and firmware update capability via the internet.

Technical Specification
The GOOSEMeter ONE includes a transflective color TFT display, rotary encoder, and LED indicators. It supports USB and Ethernet communications, with firmware updates available. The device has a RAM capacity of 32 MB for GOOSE messages and a flash storage capacity of 12 MB. It operates within a temperature range of 0-50ºC and is compliant with CE-marking directives and ISO-9001 standards.
