Fuse & Breaker Testing
AC Current Sources are useful in a variety of applications where precision is required; including precise evaluation of circuit breakers, overload relays, heating elements and non-destructive testing of fuses. The arbitrary waveform capability of the CS makes it possible to test these devices under real-world circumstances with harmonically rich current waveforms. Protection devices that are specified to withstand specific current levels for certain durations can be tested easily with the CS current source by programming specific current levels, frequencies, and durations using the transient programming system.
