Report on Test of “Agastat” Time Delay Relay

摘要

The object of the test was to determine:n(a) The suitability of the "Agastat" relay for Naval use.n(b) The effects of temperatures in excess of 35° C. upon the operation of the relay, a previous relay having failed to operate at temperatures above 35° G. as reported in ref.(b).n(c) The effects of temperature increase on the resistance of the relay coil to determine if the gas or the magnet coil was　affected primarily to cause the failure of the relay.
