(inches), and of meeting unusually onerous interrupting-test duty requirements. The results are summarized of short-circuit tests conducted on experimetal arc chutes containing a variety of metallic and nonmetallic baffles and cooling rods. Their performance characteristics are illustrated by oscillograms correlated with excerpts from high-speed cine film records.","PeriodicalId":118797,"journal":{"name":"Transactions of the American Institute of Electrical Engineers.

Aging tests made in oil under carefully controlled conditions have shown TherMEcel to have much greater thermal stability than electrical grade kraft paper. The necessity of evaluating absolute strength, as well as the retention of several physical properties during aging, is emphasized. Toughness is suggested as a good evaluation parameter. TherMEcel can be produced as tape, paper, and board.","PeriodicalId":118797,"journal":{"name":"Transactions of the American Institute of Electrical Engineers.
