Abstract
To support the recommendation of shifting transient monitoring from voltage surges to current surges, the paper presents experimental results as well as numerical modeling results demonstrating two mechanisms causing an apparent decrease of surge activity in low-voltage ac power circuits. The first mechanism is the proliferation of surge-protective devices, a situation which is by now well recognized. The second, which should also have been recognized, apparently escaped scrutiny so far: the proliferation of electronic appliances containing a switch-mode power supply that effectively places large surge-absorbing capacitors across the ac power systems.Proceedings Title
