High voltage surge arresters, also called lightning arresters, are electrical devices designed to protect high voltage systems and equipment from voltage surges or transients caused by lightning strikes, switching operations, or other sources. They are typically installed in power transmission systems, substations, and industrial facilities, where high voltage is used.

YF POWER's commitment to innovation and customer satisfaction has made the brand a trusted partner for customers worldwide.
The working principle of high voltage surge arresters is based on the principle of providing a low impedance path for transient currents caused by high voltage surges. High voltage surge arresters operate by using non-linear resistance elements made of metal oxide varistors or silicon carbide. These materials provide a high resistance under normal operating conditions but switch to a low resistance state in the presence of high voltage surges. When a surge occurs, the surge arrester conducts the excess energy to the ground, reducing the peak voltage level that the equipment is exposed to, ensuring the equipment is protected from damage. The high voltage surge arresters can also operate with high energy, fast response time, and frequent surge stress, making it a reliable and effective protection solution for high voltage power systems. Proper installation and testing of high voltage surge arresters are essential for effective performance.
High voltage surge arresters exhibit several characteristics that distinguish them from other surge protection devices:
1. High Energy Absorption: High voltage surge arresters are designed to handle high energy surges and transient currents without causing damage to equipment.
2. High-Speed Response: High voltage surge arresters have a fast response time, providing immediate protection against high voltage surges.
3. Low Voltage Protection: High voltage surge arresters can also provide low voltage protection, making them suitable for electronic equipment, such as computers and televisions.
4. Environmental Stability: High voltage surge arresters are resistant to harsh environmental conditions, making them suitable for use in various industries, including wind power and oil and gas.
Overall, the characteristics of high-voltage surge arresters make them a reliable and effective option for surge protection in a variety of applications. Proper selection, installation, and maintenance of high-voltage surge arresters are essential for their optimal performance.
