Modular Software and Advanced Algorithms
Our patented D-PMU platform converts raw data into actionable insights: real-time monitoring, DER control, fault management and predictive analytics. The software is modular, scalable and fully interoperable with existing systems and can leverage data from third party devices.
SmartGRID Technologies Approved PMUs are High-Precision, Fast, Time-Synchronized Measurements
SmartGRID Technologies PMUs measure voltage, current and phase angle at unmatched frequency and synchronization levels. They are fully compliant with IEEE C37.118 and IEC/IEEE 60255-118, with accuracy that is 100 times the standards.
3-Phase Linear State Estimation Algorithms
Our state estimator delivers real-time visibility across distribution networks, including topology identification and island detection. It ensures high availability and automatically handles bad or missing data.
Advanced Fault Detection and Fault Distance Indicators Algorithms
Zaphiro’s proprietary algorithms combined with high-frequency PMU data enable unprecedented fault detection capabilities—even for low-magnitude or fast-transient events. They work across all network
conditions and integrate seamlessly with protection, FLISR and predictive maintenance schemes.
Power Quality Monitoring Algorithms
Our power quality monitoring algorithms continuously assess voltage, current, frequency and harmonics with high temporal resolution. They detect and classify disturbances such as sags, swells, transients and unbalances, helping utilities ensure compliance with regulatory standards and improve overall service quality for end-users.
Predictive Maintenance Algorithms
Zaphiro’s predictive maintenance algorithms analyze real-time and historical data from PMUs to detect incipient faults and in general early signs of asset degradation. By identifying trends and anomalies in electrical parameters, our system helps utilities anticipate failures before they occur, optimize maintenance schedules and extend the lifespan of critical infrastructure.
SCADA/Control Room Integration
SynchroGuard seamlessly integrates with existing SCADA and DMS platforms, delivering high-frequency, time-synchronized data directly to control rooms. Operators gain enhanced situational awareness, faster fault localization and improved decision-making—without disrupting existing workflows. This integration supports both legacy and modern systems, ensuring a smooth transition to smarter grid operations.
Installation Simplicity and Safety, Minimal TCO
Our solution features non-intrusive, flexible Rogowski coil sensors and a compact, easy-to-install cabinet that can typically be deployed in under an hour per substation—without service interruptions. The system’s intuitive interface and low-maintenance design ensure straightforward operation. Together, these advantages contribute to one of the lowest Total Cost of Ownership (TCO) on the market, making it ideal for retrofit projects or deployments with limited resources.
Real-time Grid Monitoring & Supervision
Obtain full grid observability in real-time, including the estimation of the status of substations not directly monitored. This allows for proactive management and predictive maintenance, all with a limited investment in substation equipment.
Observability on MV grids is often limited to primary substations. The increasing penetration of Distributed Renewable Energies (DERs) creates bidirectional flows and increased unpredictability, making real-time understanding of the network difficult.
By installing a limited number of PMUs in strategic nodes (only 10–20% measurement coverage), SynchroGuard uses PMU-based state estimation to provide comprehensive visibility on voltages, current/power flows and phase angles in real-time. This data can be visualized in your existing SCADA.
Outage Management
(FLISR)
Drastically reduce the duration and frequency of blackouts. Automatic fault location allows for rapid dispatchment of crews or automation of FLISR (Fault Location, Isolation, Service Restoration) schemes. This directly improves power supply continuity and helps avoid penalties.
Ageing grid infrastructure and extreme weather conditions, among others, reduce network reliability and regulatory pressure to improve performance indicators (SAIDI/SAIFI) is increasing. Locating faults can sometimes take days without the right information.
SynchroGuard enables automatic and precise fault location in less than a second, using novel techniques based on PMUs. This works for all types of faults (permanent, incipient, single-phase, multi-phase) and different neutral treatment conditions, with a typical accuracy of 100m. Alerts can be integrated into SCADA/ADMS systems.
Power Quality
Monitoring
Automatic root-cause identification and analysis is possible thanks to PMU measurement synchronization. The solution allows monitoring and managing power quality without massive equipment investments.
The integration of inverter-based resources (like solar PV) creates voltage issues which undermine system reliability, and national and international regulations require compliancy with Power Quality (PQ) Std.
SynchroGuard detects and classifies voltage and frequency events (dips, swells, interruptions) based on PMU measurements. It monitors key PQ KPIs (voltage profiles, unbalances, etc.) even in substations not directly equipped with PMUs thanks to estimation. Periodic analysis reports can be generated.
Congestion
Management
Rapidly identify grid bottlenecks and prioritize reinforcement or expansion of the most congested areas. This facilitates the integration of renewables and helps avoid costly network reinforcements.
Distribution grids, often designed several decades ago, are not capable of coping with the increasing electrification trends and integration of DERs. Grid managers are often not aware of actual congestion until a failure happens.
SynchroGuard monitors congestions on transformers and lines through state estimation. It provides real-time alerts in case of dangerous conditions and generates periodic analysis reports.
Predictive & Condition
Based Maintenance
Anticipate failures before they occur, evaluate time to failure and optimize maintenance scheduling using real-time data, historical trends and intelligent analytics. Improve asset longevity, reduce unplanned outages and cut operational costs with minimal additional infrastructure.
Traditional maintenance strategies are often reactive or follow fixed schedules, leading to inefficient resource use and a higher risk of unexpected failures. In modern distribution grids, especially with increased DER integration, incipient faults, such as partial discharges, insulation degradation, or intermittent contact issues, etc., can go unnoticed until they cause major disruptions.
SynchroGuard uses high-resolution PMU data in combination with machine learning and artificial intelligence algorithms to detect early signs of asset degradation and incipient faults. These include anomalies such as voltage and current oscillations, unbalances, harmonic distortions, or unusual phase angle shifts. By identifying subtle deviations from normal grid behavior, SynchroGuard enables predictive maintenance with actionable insights. Utilities can schedule interventions based on asset condition rather than time, improving grid reliability and reducing maintenance costs.
Parallel Switching
Operations
Estimation-based synchrocheck verification is possible at any node in the network. Automatic estimation of circulating currents allows limiting power losses and voltage variations. This functionality integrates seamlessly with existing SCADA/ADMS systems.
Reconnection of grid portions supplied by two HV-MV substations can generate synchronization issues, unwanted circulating currents and potentially damage equipment.
By installing a limited number of PMUs (at least in HV-MV substations and ideally in some strategic MV-LV substations), SynchroGuard performs PMU-based synchrocheck verification to avoid protection misoperations. It also allows automatic estimation of circulating currents.
