W912EF26RA003 Amendment 8 Westinghouse Test Report for 7000374 7000942 and 7001750.pdf

These documents are factory test reports from Westinghouse Electric Corporation for Class OA/FA Shell Form Power Transformers manufactured for the U.S. Army Corps of Engineers under General Order No. PO-83650, Shop Order No. 1M1408.

The transformer specifications are rated at 164,000/218,666 KVA with voltage ratings of 288,684 to 13,200 volts, single phase, 60 cycles (or 60 Hertz in later reports). Serial numbers include 7000734, 7000942, and 7001750. The test reports document comprehensive factory testing conducted between February 1957 and November 1971, including resistance measurements, exciting current, load loss and impedance measurements, insulation tests, applied potential tests, power factor analysis, ratio tests, cold resistance measurements, pressure tests, and ASA impulse tests with surge current measurements. Key performance data includes load loss watts ranging from approximately 124,000 to 298,000 watts, no-load loss watts between 89,000 and 224,000 watts, impedance percentages from 14.96% to 15.11%, and efficiency ratings between 99.70% and 99.7262% at 75°C with 100% power factor. All transformers successfully passed insulation and pressure testing at 10 pounds per square inch for six hours. Testing was conducted at the Muncie Plant and certified by Fellow Engineer R.S. Farmer.
