Failure analysis & diagnostics of power transformer using dielectric dissipation factor
2008 Edition, April 1, 2008 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

The quality of power transformer insulation system is evaluated on a routine basis by measurement of the dielectric dissipation factor and capacitance of the insulation system. The use of dielectric dissipation...

Panel 9 - diagnostics vs failure analysis
2004 Edition, January 1, 2004 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

This work discusses about the opportunity for diagnostic tools and physical failure analysis. The failure of chip, cause for the failure, and its diagnostics are also focused. The diagnostic tools attempt to isolate the cause for the...

IC failure analysis: the importance of test and diagnostics
1997 Edition, Volume 14, July 1, 1997 - IEEE Computer Society

Continuous improvements in yield, reliability, time to market, and customer satisfaction all benefit from quick corrective action through root-cause failure analysis. The author reviews software- and hardware-based diagnostic methods for fault localization, the first and most...

Towards Vehicle-Level Simulator Aided Failure Mode, Effect, and Diagnostic Analysis of Automotive Power Electronics Items
2020 Edition, March 1, 2020 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

The increasing demand for Electronic Control Units able to perform safety-relevant tasks leads the automotive industry to find novel verification methodologies, capable to decrease the time-to-market and, at the same time, to improve the quality of the assessment. The ISO26262:2018...

Transformer common test description for condition management
2016 Edition, October 1, 2016 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

This paper presents a description of the common tests used in power transformers health index assessing. Power transformer condition evaluation is bases on humidity, acidity, dielectric strength, dissipation factor, dissolved gas...

Evaluation of Capacitance and Dielectric Dissipation Factor of Distribution Transformers - Experimental Results
2018 Edition, June 1, 2018 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

This paper aims to evaluate the capacitance and the dielectric dissipation factor (DF) of brand new distribution transformers tested in the past two years at LAT-EFEI High Voltage Laboratory. Evaluation proposed consists to classify the capacitance between...

Diagnostic resolution improvement through learning-guided physical failure analysis
2016 Edition, November 1, 2016 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

An accurate and high-resolution diagnosis enables physical failure analysis (PFA) to identify and understand the root-cause of integrated-circuit failure. Despite many existing techniques for improving diagnosis, resolution is still far from ideal, which hinders PFA and...

An overview of CMOS VLSI failure analysis and the importance of test and diagnostics
1996 Edition, January 1, 1996 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

This paper reviews the logic failure analysis process and the critical need for design-for-diagnostics. The use of flip-chip packaging will render hardware-based diagnostic techniques from the front side of the die obsolete, e.g., liquid crystal,...

A new diagnostic method to support standard frequency response analysis assessments for diagnostics of transformer winding mechanical failures
2014 Edition, Volume 30, March 1, 2014 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

The standard frequency response analysis (FRA) is not fully efficient for diagnostics of mechanical failures in power transformers. The article recommends that physical electrical parameters of the transformers should be analyzed in addition...

A comparative study of dielectric dissipation factor measurement under very low and power frequencies
2017 Edition, November 1, 2017 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Very low frequency (VLF) high voltage testing had been used as a simple withstand test (go/no-go). Recently, VLF diagnostic testing has emerged as a promising tool for insulation assessment of power cables. The term VLF implies testing insulation with an excitation...
