Hioki Power Quality Analyzer PQ3198
For Lightning & Surge Protection System Effectiveness Monitoring

Lightning can cause a sudden high voltage spikes, also known as transient over-voltage. A surge protection system protects electrical systems and equipment from this transient voltage and also surge from load switching through surge protection devices. Transient over-voltage from lightning carries voltage up to 6000V within less than 1 millisecond duration to low-voltage consumer network. Hence, the failure of surge protection devices to function to its designated rating during a lightning strike can lead to costly damages.

In this article, we show you how Hioki latest improved innovation, the Power Quality Analyzer PQ3198 is able to perform continuous data logging of voltage and hence monitor the effectiveness of surge protection devices.
