Each surge arrester metal oxide resistor assembly undergoes rigorous testing to verify surge arrester DC leakage current compliance with IEC 60099-4 and IEEE C62.11 standards.
Specialized Housing Technologies
Choose between polymer surge arrester designs for contaminated environments or traditional porcelain surge arrester configurations for standard applications. Our composite surge arrester technology combines the reliability of metal oxide varistors with advanced polymeric housing, while anti-pollution surge arrester variants excel in coastal installations.
Frequently Asked Questions:
What determines surge arrester rated voltage selection?
The surge arrester rated voltage must exceed system maximum voltage by 25% to ensure proper surge arrester MCOV coordination.
How does surge arrester norminal discharge current affect protection levels?
Higher discharge current ratings provide better energy absorption but require larger surge arrester creepage distance for proper insulation coordination.
