What is the primary purpose of a surge protector in a 3-phase system?

The primary purpose of a surge protector in a 3-phase system is to safeguard devices from voltage spikes and transients. Voltage spikes can occur due to various reasons such as lightning strikes, switching of electrical devices, or fluctuations in the power supply. These spikes can significantly exceed the normal operating voltage and potentially damage sensitive electronic equipment.

Surge protectors work by diverting excess voltage away from the devices connected to the power source, thereby preventing them from experiencing the harmful effects of these transient voltages. They ensure that the voltage remains within safe limits, thereby extending the lifespan of electronic equipment and ensuring reliable operation.

Using a surge protector is critical in environments with sensitive equipment or where unexpected electrical surges are likely, highlighting its essential role in maintaining the integrity of the connected devices in a 3-phase electrical system.
