Abstract :
DURING 1954, a radiation pyrometer was developed by the Franklin Institute in conjunction with the Philadelphia Electric Company. It was constructed for the purpose of measuring in-service temperatures on the amortisseur windings of the 25-cycle single-phase generators of two large frequency changers. The temperature measurements which were made with this instrument were the latest in a long series of investigations in connection with recurrent amortisseur winding failures apparently caused by a combination of temperature, stress, and time.
