What is the basic loading condition for transformer and its life expectancy?
When a Transformer is operated under ANSI / IEEE basic loading conditions (ANSI C57.96), its normal life expectancy is about 20 years. The ANSI / IEEE basic loading conditions for Transformer ar?
i. The Transformer is continuously loaded at rated kVA (kilo Volt Ampere) and rated Voltages (Transformer must be operated at the rated Voltage and kVA)
ii. The average temperature of the ambient air during any 24-hour period is equal to 30°C (86 °F) and at no time exceeds40°C (104 °F).
iii. The height where the transformer is installed,does not above 3300 feet or 1000 meters.
