Power system synchronization with sub-microsecond accuracy to ensure grid stability, data traceability, and operational efficiency.

As power grids evolve toward intelligence and decentralization, precise time synchronization becomes the backbone of system reliability. California Triangle provides ultra-accurate, standards-compliant timing solutions tailored for smart grids, substations, and utility communication networks.

Why Timing Synchronization Is Critical for Power Systems

In modern power utilities, everything from fault detection to control signal dispatch depends on synchronized time. Without precise timing, utilities face:

• Incorrect sequence-of-events logging

• Fault mislocalization during outages

• Instability in wide-area protection and automation

• Regulatory non-compliance with IEEE C37.118, IEC 61850, or NERC standards

Sub-microsecond time synchronization is essential to maintain safe, stable, and scalable power infrastructure.

Core Use Cases for Smart Grid Timing

Phasor Measurement Units (PMUs) and WAMS

Ensure precise synchrophasor timestamping for real-time monitoring, grid state estimation, and fault detection.

IEC 61850 Substation Automation

Enable GOOSE messaging, sampled value (SV) streams, and IED coordination with PTP-synchronized timing.

Distributed Energy Resources (DER)

Synchronize solar farms, wind turbines, and microgrids to central control using GNSS and PTP hybrid timing.

Load Balancing and Demand Response

Accurate timing ensures proper time-stamped logging for energy flow, consumption patterns, and grid demand forecasting.
