Time synchronization and critical network infrastructure
Applied in sectors
Bitstream — a Polish manufacturer specializing in network infrastructure for critical environments — produces the synchronization and connectivity layer that enables the most time-demanding applications: IEC 61850 digital substations, ETCS railway signaling, and high-precision C4ISR systems. Their time servers, industrial switches, and MACsec-encrypted routers are designed to operate without interruption in extreme industrial conditions — from -40°C to +70°C, with severe EMI, and without preventive maintenance for years.
The TS-3000 is the reference IEEE 1588v2 (PTP) grandmaster for high-voltage electrical substations. It receives GPS/GNSS signal with 1+1 input redundancy and distributes time with sub-100 ns precision to all protection relays and IED units in the substation. It supports the IEC 61850-9-3 Power Utility Automation (PUA) profile and the IEEE 1588-2019 Power Profile, both required by major transmission companies for 220 kV and 500 kV installations. The compact TS-1000 implements the ETCS profile for railway signaling, with IRIG-B and 1PPS outputs for trackside equipment synchronization. ISS-series switches implement HSR/PRP ring redundancy (IEC 62439-3) for zero packet loss during link failure — critical in substation protection networks. IMR-series routers add MACsec encryption (IEEE 802.1AE) for encrypted communications between substations and SCADA control centers.

Time synchronization is invisible when it works and catastrophic when it fails. In an IEC 61850 digital substation, line differential protection relays (87L function) compare current measurements taken simultaneously at both ends of a line to detect internal faults. If the clocks at opposite ends differ by more than 1 ms, the 87L function can generate spurious trips — opening the line with no actual fault present. In railway signaling, ETCS calculates the movement authority (MA) for each train based on timestamped positions and speeds. A ±3-minute deviation between system clocks — a common scenario before Bitstream installation on Peru's Central Railway — generates traffic conflicts and triggers emergency stops.
In Peru, the Central Railway Lima-Cerro de Pasco case illustrates the impact: GPS-PTP synchronization with Bitstream TS-1000 reduced system clock deviation from ±3 minutes to less than 1 ms, eliminating movement authority conflicts as a source of operational disruption. For the SEIN grid, TS-3000 grandmasters are the solution for 220 kV-500 kV transmission substations where line differential protection requires microsecond-level synchronization between equipment separated by tens of kilometers.
