Overvoltage protection is a safety measure designed to prevent electrical devices from being damaged by excessive voltage. This can occur due to various reasons, such as lightning strikes, power surges, or faults in the electrical system. Devices like surge protectors and voltage clamping devices are commonly used to absorb or redirect the excess voltage, ensuring that the connected equipment remains safe. Implementing overvoltage protection is crucial for both residential and industrial settings. It helps maintain the longevity of electrical appliances and reduces the risk of fire hazards. By using proper protection methods, users can safeguard their investments and ensure a stable power supply.
