Dissolved Gas Analysis (DGA) is one of the most reliable methods for identifying internal transformer faults. By analyzing the gases dissolved in transformer oil, we can detect signs of overheating, electrical discharges, or arcing. Using real-time online DGA systems, we continuously monitor the gas concentrations, providing early warnings about potential problems. This analysis helps us identify specific fault conditions such as thermal faults, electrical faults, or mechanical issues, allowing for timely corrective actions.

Partial discharge is a sign of insulation breakdown, and its detection is key to diagnosing faults in power transformers. Circuitech uses advanced Partial Discharge (PD) testing methods to detect small electrical discharges within the transformer insulation. By identifying areas of insulation degradation early, we can help prevent catastrophic transformer failure and improve operational reliability.

Tan Delta testing is an important diagnostic technique for assessing the insulation health of power transformers. It measures the dielectric losses in the transformer’s insulation system, providing insights into the condition of the insulation material. Elevated Tan Delta values can indicate potential breakdowns in the insulation, which could lead to transformer failure. We offer online Tan Delta testing to monitor the condition of transformer insulation continuously, helping to detect faults early and reduce maintenance costs.

Transformer oil plays a vital role in cooling and insulating the transformer. Over time, oil can degrade or become contaminated with moisture, gases, or particles. Circuitech performs oil quality analysis to check for contaminants that could impair the transformer’s performance and lead to faults. By conducting regular oil tests, we ensure that the transformer oil remains in optimal condition and is free from harmful substances, preventing premature failure.

Overheating is one of the most common causes of transformer failures. Circuitech uses infrared thermography (thermal imaging) to detect hot spots and abnormal temperature variations in transformers. By identifying areas with excessive heat, we can pinpoint potential electrical faults or poor connections that could lead to transformer damage. Our thermographic inspections are non-invasive and provide real-time data to monitor temperature changes over time.

In addition to advanced diagnostic techniques, Circuitech offers visual and mechanical inspections to check for external signs of transformer faults. This includes assessing components such as bushings, tap changers, bushings, and gaskets. Physical damage or wear and tear in these components could lead to operational failures. Regular inspections help prevent costly downtime and ensure transformers are in optimal condition.

Once a fault is detected, identifying its exact location and root cause is essential for taking the right corrective actions. Circuitech’s team utilizes advanced diagnostic tools to pinpoint the source of the problem, whether it’s related to electrical, mechanical, or insulation issues. By performing thorough root cause analysis, we help clients prevent similar faults in the future and optimize transformer performance.
