Flexibility
There are major changes to substation design philosophies
underway, and utilities are looking toward the future for what
the substation architecture will look like in years to come. To
ll the needs of a changing environment, the GridTime™ 3000
GNSS Time Server has exible licensing options that allow
utilities to only enable the features they need, when they
need them.
Electrical Protected
It is critical that all devices continue to operate when power
surges are present in a substation network. All ports on the
GridTime 3000 GNSS Time Server are electrically isolated up
to 2.5 kV to ensure continued operation if an unexpected
surge or transient occurs.

Resilience
Although issues within any type of network are bound to
happen, the ability to ride out and recover from these issues
is important.
Resilient timing is critical in any modern substation. The
GridTime 3000 GNSS Time Server consists of multiple
safeguards to ensure it can withstand unpredictable and
adverse conditions. Mitigation techniques include malicious
software checking, advanced holdover options, hardened
components, advanced holdover options and compliance to
IEC 61850-3:2013 environmental standards.
Redundancy
The GridTime 3000 GNSS Time Server oers redundant
power supplies, optional additional oscillators, rmware
upgrade, downgrade verication and Parallel Redundancy
Protocol (PRP) support to keep a network up and running.
Security
Cyber security threats are on the rise, and network
administrators around the world are working to protect
their networks and the companies that own these networks.
The transition to digital interfacing and networking has
required many power utilities to protect themselves and their
customers from malicious attacks. The GridTime 3000 GNSS
Time Server uses secure boot and industry-standard access
control to ensure only those with adequate permission can
access, congure and control the system.
Port Density
As networks evolve and grow, the number of connections
needed will also continue to grow. We have outtted the
GridTime 3000 GNSS Time Server with the largest number
possible.
Industry-Standard Protocols
The power industry uses several standardized timing protocols.
The GridTime 3000 GNSS Time Server has the exibility to
support all relevant timing needs from a single platform.
Key protocols supported include:
Precision Time Protocol (PTP)
Network Time Protocol (NTP)
IRIG-B (B004–B007, B124–B127)
Serial time strings
T1/E1/J1
Programmable pulses (eg. PPS, PPM, PPH)
DCF-77
High-Speed Ethernet Interfacing
The GridTime 3000 GNSS Time Server has 10 dedicated 1 Gb
Ethernet ports, each equipped with NTP and PTP capabilities.
The GridTime 3000 GNSS Time Server also supports the option
to upgrade two of the SFP Ethernet interfaces to 10 Gbps.
The GridTime 3000 GNSS Time Server also supports two
optional SFP+ Ethernet interfaces for up to 10 Gbps.
Clock Management Tool (CMT)
The GridTime 3000 GNSS Time Server uses a modern web
interface for conguration and management of the device.
The CMT is an HTTPS web-based interface that is hosted on
internal system memory.
You can connect to the CMT by using the administration
Ethernet or USB-C port and navigating to the IP address on
the display using any modern browser.
Time Accuracy Output Suppression
Within the substation, it is critical that the time provided to
end devices can be trusted to be the most accurate it can
be. We have included time accuracy output suppression in
the GridTime 3000 GNSS Time Server. If the clock deviates
past your congured threshold, it will suppress the output,
preventing the device from outputting inaccurate time and
triggering a false trip.
