Non-invasive monitoring · Grid Promwad
Your grid assetsare aging fasterthan you canreplace them.
Grid Promwad is a clamp-on monitoring platform for transformers, solar parks, wind turbines, and battery storage — no wiring into the asset, no protocol integration, no outage required. Vibration, temperature, and load anomalies detected at the edge. Deployed in hours, not months.

The challenge
500,000 transformers in Germany need replacing by 2045.
You can't replace them all.
Replacement costs have surged 60–80% since 2020. Lead times now stretch to 4 years. The only realistic strategy is to extend the life of what you have — and that starts with knowing which assets need attention now.

01 — VISIBILITY
90%
of distribution transformers · unmonitored
Flying Blind
Desire → Problem
You want to know the health of every transformer in your fleet — which ones are overloaded, which are degrading, which will fail next.
Instead, you rely on annual oil sampling and visual inspections. One in three failures occurs within 12 months of the last periodic test. Between inspections, you have no data. No trends. No early warnings. Just silence — until something breaks.
Transformation
Annual inspections. No data between visits.
↓
Continuous vibration and thermal monitoring. Know today which asset needs attention tomorrow.
02 — COST OF FAILURE
€3–11M
per transformer failure · replacement + outage
Catastrophic Failures Without Warning
Desire → Problem
You want to prevent failures — or at least get enough warning to plan a replacement on your terms.
But transformer degradation is silent. Winding insulation weakens. Core looseness develops. Cooling system efficiency drops. By the time a protection relay trips, the transformer is already destroyed. And the replacement you need? It's 2–4 years away, at double the price it was in 2020.
Transformation
Discovering failures after the fact. Emergency procurement at crisis prices.
↓
Detect degradation weeks or months in advance. Plan replacements, not emergency responses.
03 — FLEET INTELLIGENCE
500+
transformers per mid-size DSO · no fleet view
No Way to Prioritize
Desire → Problem
You want to know where to invest your limited maintenance budget — which 50 transformers out of 500 need attention this year.
But without continuous data, every asset looks the same on paper. Age-based replacement is wasteful — some 40-year-old transformers are healthier than 15-year-old ones under heavy renewable loading. Without real condition data, you're guessing — replacing assets that had years of life left, while missing the ones about to fail.
Transformation
Age-based replacement schedules. No condition data to prioritize.

Health-ranked fleet view. Invest where it matters. Defer where it's safe.
04 — RENEWABLE PARKS
43%
of solar failures · inverter-related
262 GW of Renewables, Fragmented Monitoring
Desire → Problem
You want a single view of health across your solar, wind, and storage assets — not four different vendor dashboards that don't talk to each other.
Inverter failures cause 43% of system downtime and 36% of energy losses in solar parks. Wind O&M costs consume 30% of total project costs, with 65% unplanned. Battery storage SOH estimation under real conditions remains immature. Each asset class has its own monitoring silo — meteocontrol for solar, Bazefield for wind, nothing mature for BESS.
Transformation
Separate dashboards per asset type. No cross-fleet health view.
↓
One monitoring platform for solar, wind, and storage — same sensors, same edge, same dashboard.
Running transformers, solar parks, or wind farms without continuous monitoring? Let's see what non-invasive sensors can reveal about your assets.
Start the conversation →Our solutions
Three modules. One platform.
Nothing invasive.
Grid Promwad monitors your grid assets from the outside — clamp-on sensors on transformers, inverters, and storage racks. No wiring into the asset, no outage to install. The edge gateway processes data locally. You see everything in one dashboard.
Solves: Flying Blind + Catastrophic Failures
Grid Sense
Non-Invasive Asset Monitor
Clamp-on vibration, temperature, humidity, and current sensors installed on the transformer exterior — no wiring into the asset, no protocol integration, no outage. Each sensor node connects wirelessly to a local edge gateway that runs anomaly detection models on-device.
Grid Sense detects mechanical looseness (core and winding vibration changes), thermal anomalies (overloading, cooling degradation, hot spots), load pattern shifts (renewable backfeed stress), and environmental exposure (moisture ingress, ambient stress). Not as deep as DGA — but available on every transformer in your fleet, not just the 10% you can afford to wire up.
Solves: No Way to Prioritize
FleetView
Fleet Health Dashboard
FleetView aggregates data from every sensor node — transformers, inverters, storage racks — into a single health dashboard, ranked by condition, not age.
Asset managers see which 20 assets need attention this quarter — whether those are transformers, wind turbine gearboxes, or battery racks. Maintenance planners get automated work orders when anomalies cross thresholds. Leadership gets fleet health KPIs and CAPEX deferral projections. Integration with SAP PM and IBM Maximo means Grid Promwad fits your existing workflows.
Solves: Fragmented Renewable Monitoring
Grid Park
Renewable Asset Monitor
The same clamp-on sensor kit and edge gateway that monitors transformers works for renewable assets. Vibration and thermal sensors on inverters detect degradation before failure. Current and temperature profiles on BESS racks flag cell imbalances and thermal runaway risk. Wind turbine gearbox vibration analysis catches faults up to 37 days before failure.
Grid Park doesn't replace your SCADA — it adds a predictive maintenance layer on top. One dashboard for solar, wind, and storage health, feeding into the same FleetView interface. Hybrid parks with co-located solar, wind, and storage get a single pane of glass instead of three vendor-specific portals.
How it works
Four layers. No complexity.
Data stays in your network.
No SCADA integration. No protocol conversion projects. Grid Promwad is a parallel monitoring layer — it reads the transformer from the outside and delivers health insights without touching your OT network.
Layer 1
Sense
Clamp-on vibration, temperature, humidity, and current sensors. Wireless connection to gateway. No wiring into the asset.
Layer 2
Edge
Industrial gateway (ARM/x86, IP65). On-device anomaly detection. Raw data stays local — only health indices transmitted.
Layer 3
Cloud
Fleet aggregation, trend analysis, benchmarking across assets. Hosted in EU (Frankfurt). Or on-premise if required.
Layer 4
Act
Health dashboard, alert rules, automated CMMS work orders, monthly fleet health reports for asset management.
No SCADA integration needed
Grid Promwad operates as a parallel monitoring layer. Your OT network remains untouched.
Protocols: Modbus, MQTT, OPC UA
Standard industrial connectivity. No IEC 61850 dependency. Works with existing infrastructure.
NIS2-aware design
Edge processing, encrypted transport, EU-hosted cloud. Designed to support your compliance posture.
