Smart IoT monitoring built on IS 2026 standards and IEC 61850 protocol. Secure VPN data transmission, live health index, and predictive maintenance for high-voltage transformers.
MonitEasy PTHMS (Power Transformer Health Monitoring System) is an IoT-based online condition-monitoring platform for high-voltage power transformers. It tracks physical, electrical and protection-relay parameters against IS 2026 standards, calculates a live composite health index, and transmits data over a VPN-secured IEC 61850 channel. It is designed for utilities, industrial plants and generation operators.
MonitEasy PTHMS is a smart IoT-based monitoring solution for power transformers, engineered to analyze moisture content, electrical, and physical parameters in real time according to IS 2026 transformer standards.
The platform provides a live transformer health index on the MonitEasy CloudT dashboard, enabling operators to monitor condition continuously and take pre-emptive action. Data is transmitted securely through a VPN-encrypted IEC 61850 channel to your local server or SCADA system.
Every monitoring threshold, alarm level, and protection parameter is calibrated to IS 2026 power transformer standards for accurate and regulation-ready performance analysis.
Data is fetched from the transformer via the IEC 61850 protocol and transmitted through a dedicated VPN tunnel directly to your local server or SCADA system — zero exposure to public networks.
A composite health index synthesises all monitored parameters into a single, actionable score — visible in real time on the MonitEasy dashboard, with trend lines for predictive planning.
PTHMS provides comprehensive monitoring across a wide range of critical parameters, allowing for early detection of issues, preventing failures, and ensuring optimal transformer performance.
Three distinct monitoring domains — physical, electrical, and protection — give you total visibility into every aspect of power transformer health.

Six core capabilities that make MonitEasy the preferred IoT monitoring solution for high-voltage power transformer fleets across India's utilities, industries, and generation assets.
PTHMS continuously benchmarks winding and oil temperatures against IS 2026 thresholds. When limits approach, instant alerts reach up to 5 designated stakeholders — supporting earlier intervention against insulation degradation.
Buchholz relay monitoring, PRV status, and oil quality analysis detect internal gas accumulation and pressure surges at the earliest signs of transformer stress.
Condition-based monitoring is intended to reduce cumulative thermal and electrical stress, supporting longer operational life for high-value power transformers.
VPN-secured IEC 61850 data transmission integrates seamlessly with your local server or SCADA platform — ensuring both data security and operational continuity.
A composite health index on the MonitEasy dashboard gives operators an at-a-glance status of every transformer, supporting maintenance scheduling decisions.
Load-vs-temperature correlations in auto-generated monthly reports help maintenance teams plan interventions ahead of scheduled inspection windows.
Outcomes vary by installation and maintenance regime. Case studies with baseline, intervention and measured results are available on request — view case studies.
MonitEasy PTHMS monitors every protection relay channel on your high-voltage transformer — issuing alerts before a trip occurs.
Monitors Oil Temperature Indicator (OTI) alarms and trips in real time — issuing warnings before insulation damage threshold is reached.
Tracks Winding Temperature Indicator (WTI) for continuous winding thermal status, providing early warnings before shutdown commands become necessary.
Detects low oil levels via Magnetic Oil Gauge (MOG) and immediately generates alarms to prevent cooling and insulation failures.
Monitors gas accumulation and oil movement to identify internal faults through the Buchholz relay at the earliest detectable stage.
Pressure Relief Valve (PRV) trip detection identifies abnormal internal pressure build-up and activates response workflows before equipment damage.
Tracks On Load Tap Changer position, contact wear, and operation timing to optimise voltage regulation and plan maintenance proactively.
The MonitEasy IoT architecture connects industrial sensors to a smart gateway, securely transmits data to the cloud, and delivers real-time insights through a unified dashboard.
MonitEasy PTHMS hardware is certified, field-tested, and designed to operate reliably in the demanding environments surrounding high-voltage power transformers.
| Aspect | MonitEasy PTHMS (online) | Periodic manual testing |
|---|---|---|
| Data frequency | Continuous, real-time | Scheduled intervals (e.g. quarterly/annual) |
| Fault detection | Alerts within minutes of a threshold breach | Only detected if the fault is present during the test window |
| Health visibility | Live composite health index with trend history | Single point-in-time test report |
| Integration | IEC 61850 / VPN to SCADA and MonitEasy dashboard | Typically standalone test records |
| Maintenance planning | Data-driven, based on observed trends | Calendar-based, regardless of actual condition |
PTHMS covers physical parameters (oil and winding temperature, oil level, moisture, OLTC tap position), electrical parameters (voltage, current, power factor, energy, harmonics up to the 31st), and protection-relay status (OTI, WTI, MOG, Buchholz, PRV, differential protection).
The MonitEasy health index is a composite score derived from the monitored physical, electrical and protection parameters benchmarked against IS 2026 thresholds, giving operators a single at-a-glance status with trend lines for maintenance planning.
Yes. Data is read via the IEC 61850 protocol and transmitted through a VPN-encrypted channel to a local server or SCADA system, in addition to the MonitEasy cloud dashboard.
PTHMS is designed for high-voltage power transformers, including units fitted with On-Load Tap Changers (OLTC), used by utilities, industrial plants and generation assets.
Periodic testing captures a single point-in-time snapshot, typically during scheduled maintenance. PTHMS streams data continuously and raises alerts as soon as a monitored parameter approaches an alarm threshold, rather than waiting for the next scheduled test.
Data is transmitted over a dedicated VPN tunnel using AES-256 encryption from the gateway to your local server or SCADA system, with no direct exposure to public networks.
