⚠️ Possible Faults & Anomalies

A deteriorated power capacitor may cause various issues in the equipment in which it is installed, including:

• Reduced capacitance compared with the nominal value
• Increased leakage current
• Increased operating temperature
• Increased electrical losses
• Damaged or loose terminals
• Loss of insulation
• Internal short circuit
• Open circuit in the event of component failure
• Instability or abnormal behavior in filtering circuits
• Activation of equipment protection systems

The internal electrical condition of the capacitor cannot be determined from photographs alone. Proper testing requires instrumental measurements of capacitance and insulation, together with loss and current measurements where applicable.

🛡️ Safety & Product Condition

The photographed component is a used product and may show normal cosmetic signs of previous use and handling on the metal housing and terminals. Before use, it is necessary to verify the integrity of the housing, condition of the terminals, actual capacitance and electrical insulation.

⚠️ As this is a high-voltage capacitor, it must be considered potentially charged until it has been properly discharged. Handling and testing must only be carried out using procedures and equipment suitable for the component's rated voltage.
