Power Transformer Health Monitoring - Indigenous IoT Platform

Transform substation operations from reactive maintenance to intelligent, data-driven transformer health management. Our indigenous Power Transformer Health Monitor gives every critical transformer asset continuous visibility — so small deviations never become failures.

A single 25 MVA transformer failure costs Rs. 2-3 crore and takes 8-12 hours to restore, while ageing assets already account for 18% of the installed fleet. Continuous health monitoring is no longer optional — it is essential.

Key Features & Benefits

Any Make • One Platform: Manufacturer-agnostic fleet health view across ABB, BHEL, CG, Schneider, Siemens, Voltamp or any PTR OEM
White-Box THI & RUL: Configurable weights, thresholds and transparent health logic you can audit and tune
Online + Historical Fusion: Live sensor data combined with lab DGA and oil test results, history and relay status
External Busbar + Vibration: Phase-wise HV and LV busbar temperature with delta-T analysis, plus X/Y/Z vibration trends
Explainable Health: See exactly why the health score changed and what action to take next
Fleet Risk Prioritization: Identify which asset needs attention first across your entire substation fleet
Indigenous & Customisable: Make-in-India platform with local workflows and retrofit-friendly deployment
Cost Optimisation: Add sensors selectively based on asset risk — lower total cost of ownership

Don't Just Monitor the Transformer - Manage Its Condition

Do not just monitor the transformer - manage its condition: See, Understand, Act and Verify

White-Box THI & Remaining Useful Life (RUL)

SEE: Continuous monitoring of oil & winding temperature, phase-wise HV/LV busbar temperature, moisture, dissolved H₂ gas, partial discharge, vibration and relay status
UNDERSTAND: Analyse online and historical data together to detect abnormal trends and identify the contributors to deterioration
ACT: Deviation → Risk → Action → Verify — targeted inspection, laboratory oil testing and post-action checks guided by the platform
VERIFY: Confirm improvement after every intervention for timely action, reduced risk and higher reliability
Configurable THI: Parameter scores, weights and thresholds tuned to Indian grid operating conditions — not a black box
RUL Assessment: Plan refurbishment and capital expenditure with predicted remaining useful life per asset
Fleet Risk Prioritization: Rank assets by risk and value so engineering teams always work on what matters most

Sensors and existing meters stream over RS485/Modbus to the industrial IoT gateway, then MQTT over TLS to the SSOS cloud — time-series storage, alarm engine, analytics and dashboards with role-based access and multi-channel alerts (WhatsApp, SMS, email and mobile app).

Multi-brand compatibility: ABB, BHEL, CG, Schneider, Siemens, Voltamp or any PTR OEM
SCADA ready: REST APIs, OPC-UA, BACnet and Modbus interoperability
Plug-and-play deployment: scales across 1,000+ substation assets, on-premise with 100% data sovereignty

Let's build a smarter, safer and more reliable power grid — together.
One platform. Any OEM. Your data. Your rules. Future-proof.

Traditional Approach vs With Smarter Spider

Traditional approach versus Smarter Spider - from fragmented checks to continuous intelligence

OEM-Locked vs Indigenous - Clear Difference

OEM-Locked Model

Data stored in a foreign cloud - security risk
Pay per tag / per transformer / per year
Black-box analytics that cannot be audited
Feature requests take 6 months and extra cost
Only their own brand of transformers supported
On exit, you lose all historical data
No customisation for local grid and utility practices
High false alarms, low trust in alerts
Dollar-linked licence cost that keeps escalating

Indigenous SSOS Model (POC Proven)

On-premise or utility cloud - 100% secure
Unlimited tags, assets and users
White-box, auditable THI / RUL logic
New features in weeks from the in-house team
Any OEM - true multi-brand fleet coverage
You own the time-series database forever
Tuned to your grid conditions and alarm logic
Intelligent filter - no nuisance false alarms
One-time + AMC rupee pricing model

OEM-locked: high CAPEX + high OPEX + permanent vendor lock-in
Indigenous SSOS: lower total cost of ownership, no lock-in, fully scalable
