Update 12/5/03~
Last week we went to Harvard where their power distribution team (they bought and maintain an older steam & electric generating station and serve many of their buildings with them) generously demoed the biggest Megger circuit breaker test set, rated at 60 kA with 100 kA...
The helpfulness and scope of your posts are overwhelming and we appreciate every one.
Semantics are 90 percent of searching so the links from busbar to sites dealing in circuit breaker test sets opened up an entire area that we would not have found in our searches for power source, power...
Many thanks for all your responses and the benefit of your diverse thoughts on this project.
I probably misused the term Impedance in my post, assuming it meant merely alternating current resistance, and should have simply stated the typical resistance of the sample under test, roughly 250...
For UL testing we need to equip our lab with a power source capable of pushing at least 24 kiloAmperes at any low voltage for nine seconds through our 500-MCM product under test, which has a typical impedance around 250 micro-ohms.
Some adjustability of output will be needed, as heating of...
