Power supplies
Insulation resistance
Electrical equipment; Power supplies
The ratio of the applied voltage to the total current between two electrodes in contact with a specific insulator.
Conductance
Electrical equipment; Power supplies
The reciprocal of resistance. The ratio of current passing through a material to the potential difference at its ends.
Particulate (space particulate debris)
Electrical equipment; Power supplies
The sources of spacecraft particulate debris are Earth, spacecraft, and space environments. Earth particulate is mostly dust, sand, and rocket exhaust. Sources are materials spalled by cosmic dust ...
Snapover
Electrical equipment; Power supplies
The phenomenon caused by secondary electron emission that can lead to electron collection on insulating surfaces in an electric field.
Floating potential
Electrical equipment; Power supplies
The potential a spacecraft comes to under current balance with the surrounding plasma.
Dielectric strength
Electrical equipment; Power supplies
The maximum electrical potential gradient (electric field) that an insulating material can withstand without rupture, usually expressed in volts per mm of thickness.
Frequency
Electrical equipment; Power supplies
The number of complete cycles or vibrations per unit of time.
