Rating of potential devices and suggested material for a standard

THERE has been an evident need for an exposition of the factors relating to the rating of capacitance potential devices and to their application. It is our intention to review this situation indicating the several limitations which govern ratings and application, and to offer material which may be used in t h e preparation of standards for potential devices. Vacuum-tube equipment is not covered. The authors were requested by the AIEE relay subcommittee to write a paper outlining the basis of rating for the purpose of formulating standards.
