| VARIATION OF CAPACITY WITH TEMPERATURE OF PAPER CONDENSERS G SE I.C.R SE STANDARD CONDENSER SEALED AT THE ENDS WITH ELO VARNISH I.C.R CONDENSER WITH CONDUCTING STRIPS WRAPPED IN THICKNESS OF CONDENSER TO OBTAIN BETTER COOLING-WISE. OTHERWISE STANDARD. THE POINT 'L' ON EACH CURVE INDICATES THE TEMPERATURE AT WHICH THE CONDENSER BEGINS OR CEASES TO HAVE AN APPRECIABLE LEAKAGE, JUDGED BY ITS CAPABILITY OF HOLDING OR NOT HOLDING AN APPRECIABLE STATIC CHARGE.
