Over-temp Detection with TempPatrol
Manage assets better by easily identifying failing transformers
The TempPatrol over-temp sensor is an economical, mechanical sensor that detects when the internal temperature of pole or pad-mount distribution transformers rises to extreme levels. It is a visual alert that transformers are operating over the designed temperature range, TempPatrol allows utilities to reduce unplanned outages by taking action before a transformer fails, cut operating costs by troubleshooting outages faster, and avoid repeat outages by making better decisions in the field.
PREVENT OUTAGES AND TRANSFORMER FAILURES
Build a watch list of undersized and failing ‘problem’ transformers, and schedule replacements to avoid unplanned outages. Easily identify transformers operating at extreme temperatures and reduce the risk of fires, oil spills, and damage to ancillary equipment.
TROUBLESHOOT OUTAGES FASTER
Restore power faster by quickly confirming or ruling out temperature-related transformer problems easily from the ground. Avoid repeat outages and unnecessary transformer replacement by helping crews make better decisions: re-energize or upsize.
IMPROVE ASSET MANAGEMENT
Keep right-sized transformers in service and redeploy undersized units easily. Maximize the value of rolling assets by avoiding nuisance outages and wasted time replacing good transformers. Focus monitoring equipment on problem transformers at high risk of failure.
Manage and protect assets better by proactively identifying and taking action on failing transformers
How it works
TempPatrol is compatible with pole or pad-mount distribution transformers and measures the temperature at the top oil level. When the internal temperature of the transformer reaches a pre-set threshold, TempPatrol’s visible white signal activates, alerting inspection and troubleshooting crews. When the transformer reaches an extreme temperature, TempPatrol’s visible orange signal activates.
TempPatrol’s visual indicators provide line crews with clear and easy-to-access decision-making criteria, allowing utilities to standardize procedures.
TempPatrol is triggered by a thermal element located inside the transformer, providing a reliable top oil temperature reading every time.
Easy to install and built to last
TempPatrol’s maintenance-free mechanical design is installed by your transformer manufacturer and built to last, using materials proven in the transformer environment, and at a price distribution can afford.
*When troubleshooting withTempPatrol, always follow your utility’s Standard Operating Procedures (SOPs).
How does TempPatrol save my utility money?
TempPatrol detects the internal operating temperature of a transformer and provides your line crews with a clear visual signal easily seen from the ground. TempPatrol provides an early warning to your inspection crews of a potential failure so plans can be made to either add the transformer to a watch-list or replace it before a costly unplanned outage occurs. Additionally, TempPatrol can provide key intel to Troublemen regarding the root cause of an outage that results in better decision making. This helps linemen restore power more quickly and know when to upsize in order to avoid repeat outages. TempPatrol can save utilities thousands of dollars by avoiding costly outages and troubleshooting outages faster.
At what temperatures does TempPatrol activate an alert?
TempPatrol has two over-temp alerts:
- The white alert activates when the transformer reaches a first “over-temp” threshold*
- The orange alert activates when the transformer reaches a second “extreme over-temp” threshold*

What are the risks of operating a transformer over-temperature?
Transformers operating in the normal temperature range are expected to function for approximately 20 years — every additional degree of heat will reduce this number. As the temperature rises, the increased likelihood of failure brings with it an increased safety risk to crews and the public, and increased likelihood of damage to ancillary equipment, and increased cost dealing with an unplanned outage and early transformer replacement.
How do I specify the TempPatrol sensor for my transformer manufacturer?
Getting started with TempPatrol is easy – simply update your transformers specification with a requirement to include the sensor. Here is sample language to get you started:
“Each transformer shall be equipped with the TempPatrol, over-temp sensor, produced by IFD Corporation. Installation shall be per specifications provided by IFD Corporation.”
