Protect and Enhance the Substation
Substation transformer protection can be overpriced and dauntingly engineered. TransformerIQ provides a simpler, more affordable alternative—the same functionality at a fraction of the complexity and cost.
Using the latest in sensing and communications technology, TransformerIQ monitors load (current) and top and bottom oil temperature simply and affordably. Armed with accurate, real-time data on these parameters, you can determine calculated hot spot and insulation loss-of-life rate to protect your transformer asset.
But TransformerIQ also provides full-featured, comprehensive transformer monitoring. It loads current on up to 12 windings with neutrals as opposed to the usual three, provides cooling monitoring and control, and the ability to function as a data concentrator with inputs from other monitoring devices.

Use TransformerIQ’s real-time measurements to perform the in-depth diagnosis that maximizes asset life, pre-empts issues, minimizes outages, and increases network capacity:
- Load tap changer diagnostics (Compartment heating / Motor current deviation / Position history / Tap change command failure / Daily reversals alarm / Daily operations alarm)
- Power measurement
- Fault current recording
- Insulation loss-of-life
- 3-Stage cooling control and usage monitoring
- 24-Point discrete input monitoring
- 16-Point batched alarm annunciation
- 100-Point rolling alarm history
Measure temperature and insulation aging
Using hot spot temperatures calculated or measured with fiber optic probes, TransformerIQ calculates the rate and cumulative life lost on up to 12 windings. This level of transparency maximizes both asset life, and asset health.
Monitor and control cooling
A single sensor provides full functionality, with:
- 3-Stage cooling current sensing
- Hour-meters and counters for usage recording
- Patented transformer cooling efficiency calculation
- Cooling stage swapping for even utilization
- Cooling start-up in advance of temperature rise
Monitor bushings online
Track and trend insulation failure or surface contamination (with BushingIQ). You’ll have advance warning of bushing failure—the leading cause of transformer failure—through sensors that detect early changes in voltage amplitude and phase angle.
Load tap changer diagnostics
Through retrofit, capture full trending of:
- Temperature differential alerts to heating
- Absolute position sensing for any LTC model
- Motor current during each operation
