3、hods and preferred values for metal-oxide varistor (MOV) surge protective components are covered in this standard and have the following main parameter ranges: packaging (leaded disc-type or surface mount), nominal varistor voltage (5 V to 1200 V), 8/20 surge current rating (10 A to 70 kA), and 8/20

4、 clamping voltage (10 V to 3 kV). With appropriate component selection, these components could be used for the overvoltage protection of power and signal systems having continuous ac voltages (2.5 V rms to 750 V rms), steady-state dc voltages (3.3 V to 1000 V), and peak signal feed voltages (3.5 V t

5、o 850 V). Information is given on manufacturer type testing used to determine environmental performance and rated values.

Introduction This introduction is not part of IEEE Std C62.33-2016, IEEE Standard for Test Methods and Performance Values for Metal-Oxide V aristor Surge Protective Components. This test method document has been

42、developed for the purpose of testing and comparing metal-oxide varistor (MOV) surge protective components. An MOV is a surge diverter used for limiting transient overvoltages in power and communications circuits. The interest in low-voltage varistors has grown with the trend to highly sophisticated

43、electrical and electronic devices that are exposed to surges from the environment. Initially, there were no standard terms or tests to define or compare these devices. The IEEE Surge Protection Devices Committee formed its Low V oltage Surge Protection Devices Working Group in 1970 to define these p

44、arameters. Experts were drawn from many fields in communications and power utilities, electronic manufacturers and users, test equipment manufacturers and laboratories, and producers of varistors themselves. The requirements, experiences, and vocabularies of these representatives were melded to produce this document as a guide to potential users of varistor surge protective devices.
