Problems with surge protection of electrical and electronic devices equipped with SPD and aged on a schedule basis

Jarosław Wiater

In case of electrical and electronic devices it is the lack of energy coordination between external and internal elements and devices for surge protection (SPD) that is used for their artificial ageing. Analysed is the most frequently encountered and used system consisting of a varistor surge arrester and a device subjected to protection, meeting requirements of the electromagnetic compatibility directive (bearing the mark CE). Results of the presented examinations show clearly that the surge protection efficiency without taking into account the problem of SPD energy coordination with the protected device is insufficient but encourages maintenance of the production at the time when the consumer goods market is becoming more and more saturated.
