Surge arresters are crucial components in electrical systems, designed to protect equipment from the damaging effects of overvoltage events. However, they are not impervious to failure. Understanding the common causes of surge arrester failure is essential for both electrical engineers and facility managers. By identifying these causes, preventive measures can be implemented to extend the lifespan of surge arresters and ensure uninterrupted operations. In this article, we will explore two significant factors that contribute to surge arrester failure: overvoltage events and environmental factors.

Overvoltage Events And Their Effects On Surge Arresters

Overvoltage events, such as lightning strikes or switching operations, can pose significant threats to surge arresters. These high-voltage surges can either exceed the arresters’ rated voltage or generate steep voltage rates of rise, causing stress on the arrester’s internal components.

  • Thermal stress: Overvoltage events can lead to an increase in temperature within the arrester due to energy dissipation. High temperatures can compromise the arrester’s insulation and can even result in its breakdown.
  • Partial discharge: Overvoltages can cause partial discharge in surge arresters. The repeated occurrence of partial discharge can accelerate the aging process and reduce the arrester’s overall performance.

Environmental Factors That Contribute To Failure

In addition to overvoltage events, environmental factors play a crucial role in surge arrester failure. Extreme temperatures, high humidity, and contaminants can have detrimental effects on the arrester’s performance and longevity.

Let’s take a closer look at these environmental factors:

  1. Temperature variations: Surge arresters are designed to operate within specific temperature ranges. Excessive heat or cold can affect the arrester’s material properties, leading to a decreased insulation resistance and mechanical stress.
  2. Humidity: High humidity levels can facilitate the formation of conductive paths on the arrester’s surface. This can result in leakage currents and compromise the effectiveness of the arrester in diverting surges.
  3. Contaminants: Environmental contaminants, such as dust, salt, or chemicals, can accumulate on the arrester’s surface. This buildup can lead to electrical tracking, corrosion, and decreased insulation properties.

By understanding the influence of these environmental factors, proper precautions can be taken to minimize their impact and prevent surge arrester failure. Regular inspections, maintenance, and adherence to manufacturer’s guidelines are crucial to ensure the optimal performance and longevity of surge arresters in electrical systems.
