English

partial discharge test

A Partial Discharge Tester is an instrument used to detect and analyze partial discharge activity in electrical equipment. Partial discharges are small electrical discharges or sparks that occur within insulation systems of electrical devices, like transformers, cables, circuit breakers, and generators. While partial discharges are often small and not immediately harmful, they can indicate deterioration or weaknesses in insulation material. Over time, they can lead to insulation failure, resulting in costly damage and potential safety risks.

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.
