This guide covers general recommendations for the loading of dry-type distribution and power transformers that have 80°C, 115°C, and 150°C average winding rises, and insulation systems limited to 150°C, 185°C,…
Reaffirmed 2004. General recommendations for the loading of dry-type distribution and power transformers that have 80 °C, 115 °C, and 150 °C average winding rises and insulation systems limited to…
Transformer connections, test methods, circuit configurations, and failure analysis of lightning impulse and switching impulse testing of power transformers are addressed. This guide is also generally applicable to distribution and…
Guidance on the use of outdoor power apparatus bushings is provided. The bushings are limited to those built in accordance with IEEE Std C57.19.00-1991. General information and recommendations for the…
The object of this test procedure is to establish a uniform method for investigating the effect of operating temperature on the life expectancy of oil-immersed distribution transformers. It is intended…
A test procedure is established to provide a uniform method for investigating the effect of operating temperature on the life expectancy of liquid-immersed transformers. The test procedures are intended to…
Superseded. Detailed procedures for analyzing gas from gas spaces or gas-collecting devices as well as gas dissolved in oil are described. The procedures cover: (1) the calibration and use of…
