Comprehensive Distribution Transformer Intelligence
Designed for quick, live installation and equipped with an on-board, no-maintenance power source, TransformerIQ provides the in-depth data you need to protect against overload, quickly diagnose and resolve maintenance issues, improve fault restoration time, optimize asset utilization, and predict remaining asset life.
With the increase in EVs and more volatile renewables entering the grid, the distribution system grows more vulnerable, and the threat of overload increases. Protect the grid, identify its vulnerabilities, and maximize its efficiency.
Gain operational information:
- Protect against overload and imbalance
- Accurately determine end-of-line voltage
- Smooth the integration of EVs and PVs into the grid
- Monitor transformer efficiency to quantify volt/VAR efforts
- Perform power factor correction with four-quadrant measurement of true power factor
Improve outage management:
- Improve fault isolation time with line fault information
- Set transformer alarms for temperature, overload, and voltage sag/swell
Identify major power quality issues
- Voltage and current harmonics through to the 31st harmonic on each A, B and C phase
- Voltage sag/swell
- Alarm notifications for harmonic content
- THD on the voltage and current waveforms
Intelligence From Every Link in Your Transformer Chain
Residential Transformer Monitoring Draw deep, valuable intelligence from your vast network of padmount and poletop transformers.
On the residential scale, you’ll protect from overloading in EV and PV situations. You’ll have the information needed to quantify and optimize volt/VAR efforts. With line fault information at your fingertips, you’ll improve fault isolation time as alarms provide early warning of temperature, overload and voltage sag/swell issues. Data points include:
- Fault phase indication- Fault magnitude- Fault duration
Network Vault Transformer Monitoring TransformerIQ addresses the need to affordably monitor multiple-transformers in rooms or cabinets—with discrete data for each individual transformer.
- Rogowski coil or CT current sensing- Voltage monitoring isolates at 300v (L-N)- Provisions for smart grid mesh radios
Small Power Transformer Monitoring Get the benefits of substation transformer monitoring for the small power transformer in an extremely cost-effective package designed for retrofit.
- All operational and fault information captured with feeder sensing- Measures up to four temperatures at different locations (e.g., top and bottom oil, ambient, etc.) on multiple tanks (optional)
- Calculated hot spot temperatures on all monitored windings
Protect assets. Deepen diagnostics. Enhance networks.
