Estimating DC Pollution Requirements: Comparing Simplified IEC & Statistical Approaches (Video)
Two design approaches are foreseen by IEC for AC insulator design under pollution: the simplified approach for a preliminary design or when limited information on site severity is available; and the statistical approach which in principle is more suitable for accurate final design. Read More >
Failure Modes for Surge Arresters
In most scenarios, failure occurs due to dielectric breakdown, whereby the internal structure has deteriorated to the point where the arrester is unable to withstand applied voltage, whether normal system voltage, temporary power frequency overvoltage or lightning or switching surge overvoltages.
