IEEE C57.12.58 2017 Edition, June 15, 2017 Guide for Conducting a Transient Voltage Analysis of a Dry-Type Transformer Coil
More info
Description / Abstract:
This guide applies to the equipment setup, measurement, and analysis of the transient voltage response of a dry-type transformer coil to impulse voltage.
Purpose
Transient voltage analysis is used to determine the response of various parts of the coil to a 1.2 μs × 50 μs impulse wave. This analysis can be made on specially designed prototype coils with embedded voltage leads. This testing uses significantly lower voltages than the rated BIL to expedite the test time for each data point required.
