High Potential (HIPOT) testing essentially applies a predetermined high voltage to a device under test.  If a threshold current is detected, the tester shuts down and issues an audible and visual alarm alerting the operator. 

The following items associated with the HAM6 ISC Fast Shutter system have been HIPOT tested using the indicated DC voltage.  The threshold current was set at 300uA for all measurements.

(Refer to D1400225 for cable components and D1400078 for overall shutter details)

1.  Air-side 35 foot, 6 conductor cable - Tested at 3kV in every possible wire permutation including the connector body
2.  6 Pin vacuum feedthrough (Military 5015 connector compatible feedthrough) - Tested to 1.5kV
3.  In-vacuum 10 foot, wiring harness (from flange to shutter) - Tested to 1.5kV while attached to vacuum flange
4.  Fast Shutter Coil - Tested to 1kV as a fully assembled unit (between coil and fast shutter body)

The chosen voltages are somewhat arbitrary based on an internal dialog with myself, but the maximum system voltage for the fast shutter is 500VDC.  The fast shutter operational peak current is just under 30 amperes with that peak lasting a few milliseconds.
