Description

Surge Arresters for AC Filters are specialized protective devices designed to safeguard AC filter systems in power grids, particularly in high-voltage transmission and distribution networks as well as converter stations. These arresters are installed in conjunction with AC filters, which are responsible for mitigating harmonic currents and improving power quality. They effectively suppress transient overvoltages that may occur in AC filter circuits due to lightning strikes, switching operations, system faults, or harmonic resonance. By rapidly diverting surge currents to the ground and clamping the voltage to a safe level, Surge Arresters for AC Filters prevent damage to filter components such as capacitors, reactors, and resistors, ensuring the stable operation of the AC filter system and thus maintaining the overall power quality and reliability of the power grid.

Features

• Optimized for AC Filter Circuits：Tailored to the specific electrical characteristics of AC filter systems, including the presence of harmonic frequencies and unique impedance properties. They are designed to handle the particular overvoltage scenarios that arise in these circuits, providing precise and effective protection without interfering with the normal filtering function.

• Excellent Harmonic Resilience：Capable of operating stably in environments with high harmonic content. The internal components, especially the metal oxide varistors (MOVs), are designed to withstand the stress caused by harmonic currents and voltages, ensuring reliable performance even in the presence of significant harmonic distortion.

• Rapid Response to Transients：Equipped with high-performance MOVs that have an ultra-fast response time to transient overvoltages. This quick reaction is crucial in AC filter systems, where even short-duration overvoltages can damage sensitive components, ensuring that surges are clamped before they can cause harm.

• High Energy Absorption Capacity：Able to absorb large amounts of energy from severe surge events, such as those caused by direct lightning strikes or major system faults. This high energy handling capability ensures that the arrester can effectively mitigate the impact of such events, protecting the AC filter components from damage.

• Durable and Weather-Resistant Construction：Housed in robust materials, such as composite silicone rubber or porcelain, which offer excellent resistance to environmental factors including UV radiation, extreme temperatures, moisture, and pollution. This durability ensures long-term reliable operation in both indoor and outdoor installations, reducing maintenance requirements.

• Low Leakage Current：Exhibits minimal leakage current during normal operation, which helps to minimize power loss and prevent unnecessary heating. This is important for maintaining the efficiency of the AC filter system and ensuring that the arrester does not interfere with the normal operation of the filter.

• Compliance with Industry Standards：Manufactured in accordance with relevant international standards, such as IEC and IEEE standards, ensuring that they meet strict performance and safety criteria. Compliance with these standards guarantees that the arresters are compatible with AC filter systems worldwide and can be relied upon for effective protection.

• Easy Integration with Filter Systems：Designed with dimensions and mounting configurations that allow for easy integration into existing AC filter systems. This simplifies installation and ensures that the arrester can be seamlessly incorporated into the filter circuit without requiring major modifications to the system.
