2. Key Benefits
This section provides an overview of the GridTime
™
3000 GNSS Time Server’s key features.
2.1 Flexibility
With much of the power industry undergoing a digital migration, many utilities are transitioning from legacy time code
distribution to Ethernet-based time distribution. Consequently, time distribution requirements are evolving.
This is why the GridTime 3000 has been designed with a licensable hardware model, where licenses are loaded onto
the device to enable specific ports and functionality.
This way, if the time distribution needs change, and a legacy timing bus system is replaced with an Ethernet time
distribution system or a hybrid system, licenses can be purchased to enable the Ethernet timing functionality on the
GridTime 3000, instead of purchasing an entirely new time server.
2.2 Redundancy
As the power industry involves mission critical applications, ensuring equipment remains operational in the event of a
system failure is essential. This is why having redundant backup systems in place is crucial for bolstering resiliency
against failures.
For this reason, the GridTime 3000 includes multiple features, and expansion options for adding additional
redundancy.
These include:
• Parallel Redundancy Protocol (PRP) support on all Ethernet ports.
• Dual firmware images - the device stores a primary firmware image and a backup image.
– If the primary image cannot be booted, the backup image is booted instead, which becomes the new
primary image.
– This protects the device against upload of malicious or corrupted firmware.
• A dual oscillator expansion option. This offers resiliency in the event of an oscillator failure. See 3.3. Hardware
Options .
• A dual band GNSS receiver. This offers protection if GNSS spoofing or jamming is detected on one of the GNSS
bands.
2.3 Reliability
To meet the needs of the power industry, the GridTime 3000 has been equipped with features for ensuring robust and
reliable operation in the field.
These include:
• Isolated electrical inputs and outputs. This offers protection in the event of surges or large voltage transients.
• Field replaceable power supplies and power supply fuses. See
11.7. Power Supply Replacement
and 11.6. Power Supply Fuse Replacement .
• High temperature range tolerance on internal components: -10 ℃ ambient to ≥ +55 ℃ (14°F to 149 °F).
• Alarms ( 5. Alarms ) and detailed internal logging. The GridTime 3000's detailed alarm and logging systems allow
users to easily self diagnose and remedy issues that appear in the field.
