Methodology for the Diagnosis of Instrument Transformers and Field Lightning Devices


With the increasing occurrence of instrument transformer failures in substations, more and more companies in the electricity sector have been looking for the use of reliable evaluation and diagnostic tools that can somehow track the evolution of defects before faults occur catastrophic and sudden.

In this way, the possibility of measuring Partial Discharge (DPs) on site, using a dedicated instrumentation capable of applying signal treatment tools that separate the intense noise level from the discharge activity itself in the equipment, presented itself as a powerful tool decision-making in the management of these assets in energy companies.
