Zaphiro Technologies is a Swiss deep tech company focused on Smart Grid solutions for energy operators. The company builds SynchroGuard, a distribution grid monitoring and automation system designed to help grid operators (including DSOs, DNOs, and private MV network managers) overcome the growing operational challenges caused by distributed renewable energies, limited real-time visibility, and aging infrastructure. SynchroGuard delivers high-resolution, time-synchronized measurements to improve monitoring, reliability, operational efficiency, and the ability to integrate more solar, wind, and other DERs.
SynchroGuard uses Phasor Measurement Unit (PMU) technology adapted for distribution grids, providing comprehensive real-time visibility into voltages and electrical power flows and supporting fault location. With limited PMU installation coverage, it performs PMU-based state estimation to maintain visibility across networks. The system targets faster fault detection - described as fault location in under a second - while supporting operational workflows and easier integration with existing SCADA/ADMS environments and third-party sensors. Zaphiro positions its solution as secure by design and suitable for scalability from pilot to full deployment.
