3000 Installation Manual
Overview
The GridTime 3000 is a rack mountable precision time server for digital substation applications. Its timing protocols
and ports are enabled through license bundles (See
for a full list of all license bundles), allowing for
different functionality to be enabled as requirements change.
The GridTime 3000 has an extensive collection of different ports, including:
• Ten Ethernet ports (two RJ-45, eight SFP) on its front panel for Network Time Protocol (NTP) and Precision
Time Protocol (PTP) time synchronization
• Fifteen ports on its back panel for input of IRIG-B, and output of a range of legacy time and frequency signals
• An antenna connector on its back panel to utilize a GNSS reference.
The GridTime 3000 is suitable for use in synchronizing industrial control and supervisory control and data acquisition
(SCADA) equipment. It can provide time synchronization to many different devices simultaneously, such as Phasor
Measurement Units (PMUs), Protection Relays, Remote Telemetry Units (RTUs) and other Intelligent Electronic
Devices (IEDs) used in electrical substations and industrial control installations.
The GridTime 3000 is suitable for harsh electromagnetic environments as all its ports are electrically isolated. This
allows output wiring to feed out to operating areas in different earth potential zones without compromising site
earthing security. The isolation also protects the device from high voltage spikes.
