چکیده

To support the recommendation of shifting transienl rnonilori~ig l i w i vvltage surges lo 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 powcr supply that effectively places large surge-absorbing capacitors across the ac power systems.

Surge Voltages in Residential Power Circuits

One of the first papers reporting surge recording in low-voltage ac power circuits. Both waveform information and frequency of occurrence marked the beginning of the IEEE effort toward characterizing surge voltages in low-voltage ac power circuits, a departure from the traditional unidirectional and separate 1.2/50 and 8/20 waveforms in use for high-voltage equipment testing. In the mid-sixties...

Effects of Surge Protection Devices on Performances of PLC Systems

This paper discusses the application and the effect of the electric surge protection device (SPD) in the power line communication channel. The comparative analysis of the effect is carried out based on the performance of the power line communication (PLC) system. The SPDs used for the laboratory experiment are categorized into different types of classes depending on the surge protection level. ...

Leakage Current Analysis of Polymer and Porcelain Housed Metal Oxide Surge Arresters in Humid Ambient Conditions

This paper aims to measure and analyze of the leakage current of 20 kV polymer and porcelain metal oxide surge arresters under humid ambient conditions by applying different voltages to the arresters terminal. The characteristics of the leakage currents at that stage have been investigated when changes in the ambient humidity were introduced in an artificial fog chamber. It is assumed that magn...

The Requirements for Efficient Overvoltage Protection of Electronic Devices in Low-voltage Power Systems

Original scientific paper The increasing sensitivity of electronic devices widely used in low-voltage AC systems requires an appropriate protection against voltage and current surges. Protection of the equipment against the prospective surges is based on application of surge protection devices (SPDs). Most common situation, especially in residential buildings, is application of only one SPD at ...

A circuit simplification for AC power supply surge protection devices

As far as the design of SPDs is concerned, the need exists for simplifying its circuit structure in fulfilment of the prerequisite condition of protective reliability. The circuit simplification for SPDs is of benefit to lower the cost of manufacture and reduce the size of chassis. Considering that the traditional SPD that has been extensively used on single-phase AC power supply lines requires...
