The M5 Universal Surge Generator™ is designed to be adaptable, yet precise. Front panel plug-ins allow the device to be used for a variety of surge testing applications including standards such as FCC Part 68, Canadian 1C CS-03, Bellcore Standard GR-CORE-1089, IEEE/ANSI C62.41, and IEC1000-4-5(801-5). The surge creation is controlled via front panel switches using a softkey menu structure on the front panel LCD display. Some standards, such as those that simulate transients on telephone lines are applied directly to the load. Others such as those that simulate transients on AC power lines require coupling the surge across a power source. Powered testing of the latter type is considerably more complex, and because of that considerable detail has been supplied in this manual on power line transient testing. The sections that follow describe the test set up to be used, the use and design of the M5 Universal Surge Generator, the use and design of the 3CN single/three phase coupling network, monitoring of the resultant waveform using the TWM5, and remote computer control of the entire system with GDI’s Surge Command™ Windows1 based software.
