ensaio de descarga parcial

A Testador de descarga parcial é um instrumento utilizado para detetar e analisar a atividade de descarga parcial em equipamento elétrico. As descargas parciais são pequenas descargas eléctricas ou faíscas que ocorrem nos sistemas de isolamento de dispositivos eléctricos, como transformadores, cabos, disjuntores e geradores. Embora as descargas parciais sejam frequentemente pequenas e não sejam imediatamente prejudiciais, podem indicar deterioração ou fraquezas no material de isolamento. Com o tempo, podem levar à falha do isolamento, resultando em danos dispendiosos e potenciais riscos de segurança.

Advantages of Using Partial Discharge Analyzers​

Early Fault Detection​

Partial discharge (PD) analyzers, by identifying minor insulation issues that are not easily visible, can allow a user to act quickly to resolve the problems before they become significant faults or equipment failures.​

Prevention of Catastrophic Failures​

Partial discharge test enables the timely identification of potential issues and thus, helps in the prevention of more serious insulation breakdowns. Such unfortunate cases may cause power leakages, a total machine breakdown or the development of unsafe conditions.​

Improved Asset Life​

Checking the PD activity on a regular basis extended the electric equipment's life significantly. Deal with the problems in time that make the equipment continue to function.​

Enhanced Safety​

Detecting insulation problems early reduces risks like electrical arcing, fires, or other hazards from insulation failure.​

Cost-Effective Maintenance​

Disclaiming problems before they lead to significant losses helps save money on repairs and unplanned breaks. Here, this maintenance strategy is more cost-efficient in general.​
Think of partial discharge analyzers as the equipment that can find, diagnose, and track insulation issues in electrical equipment. They ensure that no costly equipment failures occur. This not only makes the system more stable and dependable but also elongates the equipment’s life, and finally, ensures safety. Thus, they are the heart of the predictive maintenance plan that the power generation, transmission, and industrial manufacturing sectors depend on. Done regularly, PD testing is the most efficient means to manage the dependability of power systems and reduce the unexpected failure probability.
