The IGCTs used in the power disturbance generator are each capable of interrupting up to
400A
rms
at 600V
rms
, but IGCTs with a higher rating may also be used. Additionally, IGCTs
can operate in parallel, so much higher power ratings can be achieved if needed.
The switch controller is capable of point-on-wave (POW) switching in 0.01 cycle increments.
The switch is therefore able to open at any one of 100 equally spaced points on a single cycle
of the 60Hz supply voltage waveform, remain open for between 0.01 and 9999.99 cycles, and
close at any one of 100 equally spaced points on a single cycle of the 60Hz supply voltage
waveform. Since up to 400A
rms
must be interrupted at such a precise time, the switch design
uses solid-state power electronics instead of mechanical switches.
