Practical Application and Effectiveness of Commercially Available Pulse Voltage Transient Suppressors.

摘要

Most utility power distribution systems at one time or another have random and periodic impulse voltage transients propagated throughout the system. In many cases these transients cause malfunction and physical damage to critical loads. It is possible to reduce the peak voltage levels of many types of transients to a level that most critical loads can tolerate. The report covers the results of test and evaluation of five types of commercially available impulse voltage transient suppressors. It was concluded that no one type suppressor tested meets all the requirements to completely protect critical loads,but some do effectively meet some of these requirements on a cost effective basis.
