GPS TIME SYNC
Global Positioning Systems (GPS) are used to provide a precise time reference for power system devices in an electrical network, ensuring time synchronization even across great distances.
Our Technology
Cyber Sciences specializes in precision timing for critical power applications, providing accurate, reliable data for event reconstruction.
PRECISION TIMING : SIMPLE. AFFORDABLE. SCALABLE.
For critical power applications where multiple state changes can occur within a quarter-cycle or less, a one-millisecond resolution is required for meaningful post-event analysis. To accomplish this, multiple devices with different time protocols must be synchronized which is often difficult and costly to achieve. Cyber Sciences products use technologies which work together to synchronize these devices throughout an entire power system. These technologies include IRIG-B, DCF77, NTP, and PTP (IEEE 1588). Precision Time Protocol or PTP delivers precise time synchronization within 100 microseconds over an existing Ethernet network further reducing the cost and complexity of this type application. When applied, Cyber Sciences products also produces data which is easily integrated into any power monitoring system for root-cause analysis helping to minimize risks, reduce costs and improve operational efficiency.
PRECISION TIME TECHNOLOGY
PTP (IEEE 1588)
Precision Time Protocol (PTP) per IEEE 1588 enables highly precise time synchronization over an ethernet network, due primarily to time-stamping embedded in the 1588 ethernet hardware. PTP utilizes a precise mechanism to correct for delays introduced in the network path from the time source, through multiple levels of switches, to the device clocks. This is a cost-effective solution for delivering precise time synchronization and an easier way to scale utilizing the existing network infrastructure.
IRIG-B
IRIG-B is a widely used protocol in the electrical power industry. However, for successful execution, careful consideration is needed for clock specifications, cable distances, and device limitations. Cyber sciences provide solutions that help address these concerns reducing the cost and complexity of implementation.
DCF-77
DCF-77 is not a commonly used time protocol, however, because it is a 24V signal it is distributable over longer distances compared to IRIG-B (5V). Cyber Sciences offers a DCF-77 time source and solutions to distribute it throughout a large power system, making deployment straightforward and easy.
