Why is the lightning arrester still struck by lightning after installation? 7 common installation errors to check

The lightning arresters we produce play a crucial role in safeguarding buildings and electrical equipment from the destructive power of lightning strikes. However, in certain circumstances, these devices may not function as expected, which could lead to significant damage.

1. **Improper Grounding**

Because surge arresters can only function properly with a low-resistance grounding path. Therefore, we will ensure that the design of the grounding system complies with local regulations and standards, and conduct regular inspections of the corrosion and damage of the grounding system.

2.  **Incorrect Placement**

Because the location where the lightning arresters are installed is too far from the equipment they are supposed to protect, the surge voltage will exceed the capacity of the lightning arresters. Therefore, we will install the lightning arresters closer to the equipment. Also, placing them in areas with high electromagnetic interference will affect their performance.
3.  **Inadequate Surge Capacity**

Our surge protectors have specific surge protection capacity ratings. Therefore, if the chosen surge protector does not match the potential surge levels in that area, it may not be able to protect the equipment. Usually, we conduct a thorough risk assessment to determine the appropriate surge capacity required for installation.

4.  **Poor Quality Components**

Everyone knows that using substandard or counterfeit lightning arresters can lead to failure during a lightning strike. So, it is essential to carefully select the manufacturer for production.

5.  **Neglecting Maintenance**

As time passes, environmental factors such as humidity, dust and temperature fluctuations can affect the performance of the lightning arrester. Therefore, we will conduct regular inspections and maintenance.

6.  **Ignoring System Coordination**

Our lightning arresters are coordinated with various lightning protection systems and work effectively together. This is because if the lightning arresters cannot be properly coordinated with other protective devices (such as circuit breakers and fuses), it may lead to cascading failures.

7.  **Failure to Follow Installation Guidelines**

One of the most common reasons for lightning arrester failures is failure to follow the installation guidelines provided by the manufacturer. Since each lightning arrester has specific installation requirements, we strictly adhere to these guidelines to ensure the optimal performance of the arrester.
