Fix power surge caused surge arrester failures by installing a backup surge protector. Power surges can damage surge arresters, but a backup protector can prevent this.

Power surges can be a nuisance, causing damage to appliances and electronics. While surge arresters are designed to protect against power surges, they can fail due to the overwhelming voltage of a surge. This can result in costly repairs or replacements.

To fix power surge caused surge arrester failures, it is essential to install a backup surge protector. This additional layer of protection can prevent the surge from overwhelming the surge arrester and redirect the excess voltage. We will explore the importance of backup surge protectors and how they can effectively protect your devices from power surges. So, let’s get started and ensure the safety of our electrical equipment.

Understanding Power Surge Arrester Failures

Power surge arresters play a vital role in protecting our electrical devices and equipment from sudden voltage spikes. However, there are instances when surge arresters fail to function properly, leaving our devices vulnerable to damage. In this section, we will dive into the concept of power surge arresters, how they work, and the common causes behind their failures.

What Are Power Surge Arresters?

Power surge arresters, also known as surge protectors or lightning arrestors, are devices designed to safeguard electrical equipment from voltage spikes or surges. These surges can originate from lightning strikes, power grid fluctuations, or even internal sources within our premises.

How Do Power Surge Arresters Work?

Power surge arresters act as a first line of defense against voltage surges. They typically consist of metal oxide varistors (MOV) or gas discharge tubes (GDT) that divert excess electrical energy and redirect it to the ground. By shunting these high voltage surges, surge arresters prevent the excess energy from reaching our sensitive devices and causing damage.

Common Causes Of Power Surge Arrester Failures

While power surge arresters are designed to handle voltage spikes, they can fail under certain circumstances. Understanding the common causes behind these failures can help us identify potential issues before they cause major damage. Here are some factors that can contribute to power surge arrester failures:

  • Wear and tear: Over time, power surge arresters can degrade due to environmental factors, such as temperature changes and moisture exposure. This degradation can compromise the effectiveness of the surge arrester, leading to potential failures.
  • Lightning strikes: Despite their ability to handle voltage spikes, power surge arresters can be overwhelmed by exceptionally powerful surges caused by direct lightning strikes. These extreme events can cause surge arresters to fail, necessitating their replacement.
  • Electrical faults: Faults within the electrical system, such as short circuits or ground faults, can generate sudden high voltage surges. If the surge arrester is not rated to handle these magnitudes of surges, it may fail to operate effectively.
  • Outdated technology: As technology advances, so do the capabilities of power surge arresters. Using outdated or incompatible surge arresters may result in failures, as they may not meet the demands of modern electrical systems.
