Must-read For Parallel Grooved Wire Clamp Infrared Thermography: Location Of Most Severe Overheating And Judgment Criteria

Infrared thermography is crucial for inspecting a parallel groove clamp. Detecting thermal anomalies early prevents power grid failures. Technicians must locate the exact heating points and apply correct temperature criteria during routine maintenance.

The most serious heat-generating location on the parallel slot connector

Thermal imaging shows that the most severe heating occurs at the contact interface between the conductor and the parallel groove clamp connector. Poor torque or surface oxidation increases contact resistance at this specific spot.

Secondary Hotspots to Monitor

• Bolt Junctions: Loose bolts lead to localized stress reduction.

• Conductor Entry Points: Heavy mechanical tension causes fatigue here.

Temperature Standards for PG Clamp Connector Inspection

Evaluating a pg clamp connector requires precise temperature metrics. The Delta T (ΔT) criterion determines the severity of the thermal defect based on the temperature difference between the component and ambient air.

Inspection Steps for Parallel Groove Equipment

1. Calibrate the infrared camera emissivity to 0.55 for aluminum.

2. Capture the thermal image from a 90-degree angle.

3. Record the maximum temperature at the contact point.

4. Compare the data with the reference table above.
