Problem detectedThe conductors of one of the phases are found to be at a higher temperature than the other phases. Obvious phase imbalance. Proposed solutionScrew the connection of the affected conductors down tightly and perform thermographic analysis to confirm that the anomaly has disappeared. If the critical point persists, use other procedures to determine if the problem is in the switch (if it is, change the switch). |

Problem detectedThe conductor of one of the phases is found to be at a higher temperature than the other phases. Obvious phase imbalance. Proposed solutionThoroughly check the connection with the termination of the affected conductor and perform thermographic analysis to confirm that the anomaly has disappeared. If the critical point persists, use other procedures to determine whether the problem is in termination/connector (if it is, replace it) or in the conductor (replace or check later connections). |
High operating temperature

Problem detectedThe relays are found to be nearly at regulation temperature (90ēC) due to overcrowding (or lack of separation) and poor ventilation of the housing. Proposed solutionThe operating temperature of the relays is normally high, so separation between them and proper ventilation of the housing is recommended to prevent such high temperatures being reached. Check afterwards using thermographic analysis. |

Problem detectedThe fuse in one of the phases is found to be at a higher temperature than the others. Potential start of fuse failure or phase imbalance. Proposed solutionThoroughly check the connection of the affected fuse/base and carry out thermographic analysis to confirm that the anomaly has disappeared. If the critical point persists, use other procedures to determine if the problem is in the fuse/base (replace if it is). |

Problem detectedThe high voltage blades in one of the phases are found to be at a higher temperature than the rest. Obvious fault in the blade contacts. Proposed solutionReplace the affected blade or repair it with suitable resin. Perform thermographic analysis to confirm that the problem has been solved. |
Detection of poor insulation

|
Problem detectedThe conductor of one of the phases is found to be at a higher temperature than the others. Obvious insulation fault. Proposed solutionReplace the conductor and check the source of the insulation fault to ensure that the problem does not occur again. |
Detection of poor connections

Infrared view
|
Problem detectedThe conductor of one of the phases is found to be at a temperature greater than 80ēC and hence near to the regulation maximum (90ēC). Obvious phase imbalance. Proposed solutionScrew the connection of the affected conductor down tightly and perform thermographic analysis to confirm that the anomaly has disappeared. If the critical point persists, use other procedures to determine if the problem is in the switch (if it is, change the switch) or in the conductor (replace or check previous connections). |

Problem detectedThe conductors of one of the phases are found to be at a temperature greater than 100ēC and hence higher than the regulation one (90ēC). Obvious phase imbalance Proposed solutionScrew the connection of the affected conductors down tightly and perform thermographic analysis to confirm that the anomaly has disappeared. If the critical point persists, use other procedures to determine if the problem is in the switch (if it is, change the switch) or in the conductor (replace or check previous connections). |
