The C62.42 guide series covers surge protective components (SPCs) used in power and telecom surge protective devices (SPDs) and equipment ports. This part on Gas Discharge Tube (GDT) technology SPCs covers: Component construction Characteristics Ratings Application examples The application examples ...

This guide encompasses the application of surge protective devices (secondary arresters) fromthe secondary terminals of the distribution transformer to the line side of the service equipment.

This standard applies to surge protective devices designed for application on the low-voltage supply mains (1000 V rms and less, frequency between 48 and 62 Hz) and intended to be connected at locations between, and including, the secondary terminals of the distribution transformer and the line side...

This standard covers enclosed dc power circuit breakers of the stationary or drawout type of one- or two-pole construction with one or more rated maximum voltages of 300 V, 325 V, 600 V, 800 V, 1000 V, 1200 V, 1600 V, or 3200 V for applications on dc systems having nominal voltages of 250 V, 275 V, ...

This standard adopts IEC 61000-4-15:2010, which gives a functional and design specification for flicker measuring apparatus intended to indicate the correct flicker perception level for all practical voltage fluctuation waveforms. Information is presented to enable such an instrument to be construct...
