EddyBits' IoT for transformer monitoring gives Indian utilities and industrial estates a smart transformer monitoring system covering 3-phase voltage and current, transformer oil temperature monitoring, Buchholz relay status, power factor, THD, and tap changer position — with a read-only REST API and MQTT feed for SCADA and BMS integration, for distribution transformer monitoring at scale.
A real pad-mounted transformer, sensors live on the tank and bushings, live readings on screen, data streaming to the cloud and every connected device as it runs.
Tracks Phase A/B/C voltage continuously against ground reference, flagging imbalance between phases before it accelerates transformer aging.
Monitors Phase A/B/C current and neutral current in real time, with instant overload alerts as load approaches nameplate capacity.
Tracks oil temperature and calculates hotspot rise continuously, translating a slow thermal climb into an aging-rate figure long before it threatens the winding insulation.
Watches oil level and gas accumulation rate inside the Buchholz relay, catching the slow gas buildup that precedes most internal fault trips.
Tracks power factor continuously, flagging when it drifts leading or lagging enough to warrant kVAR correction before a utility penalty hits.
Analyzes voltage and current THD continuously, identifying the harmonic signature of non-linear loads like VFDs before power quality degrades further.
Logs every tap changer operation and position, tracking cumulative mechanical wear so maintenance is scheduled off actual usage, not a fixed interval.
Tracks real, reactive, and apparent power continuously against nameplate capacity, flagging peak demand trends before they threaten transformer life.
Real-time current monitoring prevents transformer overheating. Alerts when load approaches nameplate capacity. Prevents catastrophic failure and oil degradation.
Temperature-based aging rate calculation. Oil lifespan predictions based on operational history. Maintenance scheduling before oil break-down occurs.
Detects uneven phase loads that degrade transformer life. Alerts facility managers to redistribute loads. Extends equipment life by 5-10 years.
THD monitoring identifies non-linear loads (VFDs, DC chargers, UPS systems). Recommendations for power conditioning or load rebalancing.
Monitor all transformers across industrial estate or utility grid. Compare loading patterns, efficiency ratios, and maintenance schedules. Centralized alerting system.
Machine learning models forecast remaining useful life (RUL). Recommend maintenance intervals based on actual operating conditions, not arbitrary schedules.
kWh loss calculations. Cost-to-benefit analysis for tap changer operations. Identify opportunities to reduce transformer tank temperature and extend life.
A secure read-only REST API and MQTT stream feed live values and alerts into your SCADA, BMS or EMS. Nothing that connects can control the transformer.
The full data path from your transformer to your phone, start to finish.
Current transformer clamps on the windings, voltage transformer connections on the secondary side, and an oil temperature RTD in the top-oil pocket.
A multifunction relay / IoT gateway mounted near the transformer cabin aggregates every sensor via Modbus RS-485 and sends the data to the cloud, from where it can feed your SCADA or BMS.
Data transmits via fibre optic, Ethernet, or cellular backup with TLS 1.2+ encryption — built for substations and transformer yards without reliable Wi-Fi.
Every reading is checked against thermal and electrical thresholds in real time, and made available to your SCADA or BMS through a read-only API and MQTT stream.
A developing overload, oil-temperature climb, or Buchholz gas trend reaches the maintenance team over WhatsApp and SMS, not just email.

Get a Free Site AssessmentGeneric IoT monitoring platforms are built for a global market. EddyBits is built specifically around how Indian facilities actually operate.
Most platforms default to email or app push notifications. Ours default to WhatsApp and SMS — the channels facility staff in India actually check first.
Cellular-first connectivity by default, so monitoring doesn't depend on a facility's internet infrastructure — the DG room and generator yard rarely have good Wi-Fi anyway.
Most facilities are live within 48 hours of installation, with a dedicated on-site engineering team handling setup — not a self-install kit shipped in a box.
Multi-building power distribution. Load forecasting, demand management, cost allocation per tenant.
DISCOM grid monitoring, loss reduction, feeder optimization, predictive maintenance budgeting.
Large residential/commercial complexes with multiple substations. 24/7 monitoring for tenant SLAs.
Integrated grid intelligence, demand response coordination, renewable energy balancing.
Mission-critical power. Early failure detection prevents production loss. Uptime assurance.
Step-up and step-down transformers. Generator protection, grid synchronization monitoring.
Wherever a transformer is load-bearing infrastructure, an undetected fault escalates into an expensive failure.
Multiple transformers spread across shared infrastructure means a single dashboard view matters more than any one unit's readings. Fleet-wide monitoring catches the one transformer trending toward a fault before it takes down a section of the estate.
Power factor and load monitored continuously against real thresholds, not read manually on a periodic rounds schedule, is what keeps grid-facing infrastructure reliable at the scale a utility actually operates at.
An overloaded or insulation-faulted transformer threatens the whole production line behind it, not just the unit itself. Oil temperature, Buchholz relay status, and power factor together catch a developing fault while it's still a maintenance item, not an outage.
Shared transformer infrastructure across a development is another recurring source of facility-management dispute — the same transparency argument that applies to shared DG backup power applies here, with a verifiable data trail instead of a manual reading.
A smart transformer monitoring system uses CT/VT sensors and an oil temperature RTD to track 3-phase voltage, current, oil temperature, and Buchholz relay status in real time, sending instant WhatsApp/SMS alerts and feeding your existing SCADA or BMS through a read-only REST API and MQTT.
Yes, for reading data. The platform provides a secure read-only REST API and an MQTT stream that SCADA, BMS and EMS software can use to receive live values and alerts. It cannot send control commands. Direct Modbus TCP, OPC UA and BACnet gateways are on our roadmap; DNP3 and IEC 60870-5-104 are not currently supported.
Yes. EddyBits provides a centralized fleet dashboard covering an entire industrial estate or utility grid, comparing loading patterns, efficiency ratios, and maintenance schedules from one screen.
Oil temperature, Buchholz gas accumulation, and phase imbalance are all tracked continuously. A gradual drift in any of these — the same pattern that precedes most transformer failures — triggers an alert well before it becomes a trip event.
No. Connectivity is cellular-first by default, with fibre/Ethernet options for substations — so monitoring works even at remote transformer yards with no reliable Wi-Fi.
Current transformers are 0.5S accuracy class (IEC 60044-1) and voltage transformers are 0.2S accuracy (IEC 60044-2), with sensor redundancy options available for critical transformers.
CT/VT sensor installation and gateway setup typically takes a few hours per transformer, and facilities are usually fully live on the dashboard within 48 hours.
