Abstract:
A test procedure to provide a uniform method for investigating the effect of operating temperature on the life expectancy of liquid-immersed transformers is provided. The test procedures are intended to provide data for the selection of a limiting hottest-spot temperature for rating purposes, provide data which may serve as the basis for a guide for loading, and permit the comparative evaluation of a proposed insulation system with reference to a system that has proven to be acceptable in service.
Scope:
This standard applies to the insulation systems used in all liquid-immersed distribution and power transformers. This standard provides test procedures to evaluate the thermal aging characteristics of insulation systems used in liquid-immersed distribution or power transformers. The dielectric liquid is part of the insulation system.
Purpose:
The objective of this test procedure is to establish uniform methods for investigating the effects of operating temperature on the life expectancy of liquid-immersed transformer insulation systems. The results of these test procedures are expected to a) Provide the basis for the selection of a limiting hottest-spot temperature for rating purposes b) Provide life curves that may serve as the basis for a guide for loading c) Permit the comparative evaluation of a proposed insulation system with reference to an industry proven system that has been shown to be acceptable in service
