Project Description
Precise Timing-Clocks
| The need for substation time synchronization has evolved from time-stamping basic Sequence of Events and disturbance recording information to more mission-critical needs, such as synchrophasor measurement (IEEE C37.118), sampled measured values (IEC 61850 9-2), and traveling wave fault location. These new applications demand the same reliability, security, and dependability for precise timing-clocks as other equipment designed for critical infrastructure applications, like protective relays in a substation. |

SEL Precise Timing-Clocks
The SEL-2488 receives Global Navigation Satellite System (GNSS) time signals and distributes precise time via multiple output protocols, including IRIG-B and the Network Time Protocol (NTP). With an optional upgrade, the SEL-2488 can serve as a Precision Time Protocol (PTP) grandmaster clock, as defined by IEEE 1588. The advanced capabilities of the SEL-2488 make it well-suited for demanding applications, like synchrophasors, and for substations with multiple time synchronization requirements.
