PTPGM4009

PTPGM4009 is a PTP/NTP over PRP clock that allows for multiple configurations to provide the most precise and secure timing for power utilities. It simplifies the migration to PTP without abandoning investments in NTP, IRIG-B or BITS, this way facilitating the integration, interaction, and translation of all types of signals, profiles, and protocols. It offers a dependable and fault-tolerant solution to loss of reference, network outages and power failures to enable networks to run with high precision, reliability, and efficiency.

The PTPGM4009 delivers precise and reliable timing to both legacy and next-generation devices, ensuring continuous, fail-safe operation across your power network. Designed with redundant paths and full support for modern timing distribution and transmission standards, the PTPGM4009 guarantees performance even in the most demanding grid environments.

The PTPGM4009 supports PTP and NTP over PRP, with flexible reference options such as GNSS, PTP, NTP, ToD, IRIG-B, and PPS, meeting every timing requirement across your substations.

With both Power and Telecom profiles integrated, the PTPGM4009 seamlessly bridges the gap between WAN-level Telecom networks and substation-level Power systems, simplifying integration and delivering perfect synchronization for control, protection, and data acquisition.

Engineered for network fault tolerance through PRP, the PTPGM4009 operates reliably in temperatures up to 70 °C and offers dual power supply options for maximum redundancy. The result: uninterrupted precision timing your grid can depend on.

Synchronization Testing Solutions

Synchronization testing ensures digital substations operate safely and efficiently by providing precise, standards-compliant timing. It enables accurate event analysis, reliable fault protection, wide-area monitoring, and stable integration of renewable energy into modern power grids.

Here is why synchronization testing matters for Power Grids with digital substations

• Accurate Time Stamping of Events – In digital substations (IEC 61850-based), protection relays, PMUs and IEDs all generate event data. Without precise synchronization (nanosecond level), it’s impossible to align and compare events across different substations.
• Reliable Protection & Control – Fault detection and isolation rely on coordinated protection systems. If devices are out of sync, protection relays may misinterpret faults, leading to delayed tripping or even blackouts.
• Wide-Area Monitoring and Grid Stability – PMUs need highly accurate time alignment (usually via IEEE 1588 PTP or GPS) to measure phase angles across the grid. Synchronization testing ensures these measurements are correct, which is critical for grid balancing and stability.
• Compliance with Standards (IEC 61850 / IEEE 1588) – Modern smart grids must comply with strict international standards. Testing verifies that substation equipment meets IEC 61850 and IEEE 1588 synchronization requirements.
• Integration of Renewables & Smart Grid Features – Renewable energy sources (solar, wind) cause rapid fluctuations. Precise synchronization allows advanced control algorithms to react quickly and keep the grid stable.
• Early Detection of Synchronization Issues – By testing regularly, utilities can detect clock drift, misconfiguration, or PTP distribution errors before they cause large-scale problems.
