Surge divertors, also known as surge protectors or surge suppressors, are devices designed to protect electrical equipment from voltage spikes or surges in power supply. These spikes can be caused by lightning strikes, power outages, or fluctuations in the electrical grid. Surge divertors work by diverting excess voltage away from sensitive equipment, preventing damage and ensuring the safe operation of devices. They are commonly used in homes, offices, and industrial settings to protect computers, televisions, appliances, and other electronic devices.

Surge Divertors
Definition:
Surge diverters are electrical devices designed to protect equipment and circuits from voltage surges that exceed their normal operating limits. They act as overvoltage protection devices by diverting or limiting excessive voltage to ground.
Types of Surge Divertors:
- Class A Surge Divertors: Provide high-energy absorption and are typically used in primary power distribution systems.
- Class B Surge Divertors: Offer medium-energy absorption and are common in secondary distribution systems and transformer substations.
- Class C Surge Divertors: Have low-energy absorption and are used in end-user applications, such as residential and commercial buildings.
Components:
- Non-Linear Resistance (NLR): A key component that allows current to flow during a surge but restricts it under normal operating conditions.
- Metal Oxide Varistor (MOV): A type of NLR that is commonly used in surge diverters.
- Energy Absorption Element: Provides a path for surge energy to be dissipated safely.
- Spark Gap: Used to prevent the NLR from being damaged when the surge voltage exceeds its threshold.
How Surge Divertors Work:
During normal operating conditions, surge diverters act as open circuits, allowing no current to flow. When a surge voltage occurs, the NLR becomes conductive, allowing the surge current to flow through the surge diverter and into the ground. The energy absorption element dissipates the surge energy, preventing it from reaching the protected equipment.
Applications:
Surge diverters are widely used in various electrical systems and applications, including:
- Power distribution systems
- Transformer substations
- Industrial plants
- Commercial and residential buildings
- Communication networks
- Electronic equipment
Benefits of Using Surge Divertors:
- Protect equipment from voltage surges
- Prevent electrical fires and explosions
- Increase system reliability and uptime
- Reduce maintenance and repair costs
- Enhance safety and reduce risk
