Report of Test of Foil Paper Capacitors - Potter No. 8260

Abstract

The capacity and d.c. leakage of the capacitors were measured at rated voltage when dry; the capacitors were subjected to a momentary d.c. overvoltage; and the efficacy of the seal in protecting the capacitors against salt water immersion was tested by measurement of the d.c. leakage after immersion in salt water. One of the capacitors which passed the test was cut open. A capacitor of the construction shown on the right in Plate 1 of reference (d) and which failed, was cut open to compare the construction of its terminals which are externally similar in appearance to those involved in the present test.
