Some equipment within a facility or household can generate internal surges as they start or operate. Modern electronic devices, including computers, servers, medical equipment, and telecommunications systems, are highly sensitive to voltage fluctuations.

Following are the ways in which surges affect internal systems hence having an internal lightning protection system is important.

1. Voltage Spikes and Surges:

• • Causes: Lightning strikes, power switching, and faults can lead to sudden increases in voltage.

• • Consequences: These surges can travel through power lines and potentially damage connected electronic devices.

2. Lightning Strikes:

• • Cause: Lightning induces extremely high voltage surges in power lines.

• • Consequences: Without surge protection, lightning strikes can cause severe damage or destruction to electronic devices and appliances.

3. EMI and RFI:

• • Causes: Electromagnetic Interference (EMI) and Radio-Frequency Interference (RFI) can disturb power lines.

• • Consequences: Surge protection devices filter out these disturbances, ensuring a stable power supply and protecting sensitive electronics.

4. Rapid Load Switching:

• • Cause: Quick switching of electrical loads, such as turning on/off appliances or machinery.

• • Consequences: This can cause voltage spikes, and surge protection devices suppress these spikes, preventing damage to connected devices.

5. Internal Surges:

• • Cause: Some equipment within facilities or households can generate internal surges during startup or operation.

• • Consequences: Modern electronic devices, being highly sensitive, are susceptible to damage from internal surges.

In summary, the text underscores the importance of surge protection devices. These devices play a crucial role in mitigating the impact of various factors that can lead to voltage spikes and surges. They act as a defense mechanism by filtering out disturbances, suppressing spikes, and safeguarding sensitive electronic equipment from potential damage within the electrical grid system.
