A new dynamic model for propagation of characteristic gases in transformer oil-cellulose structures due to temperature variations

A. Shahsiah; R. C. Degeneff; J. K. Nelson CEIDP '05. 2005 Annual Report Conference on Electrical Insulation and Dielectric Phenomena, 2005., 2005

Dissolved gas analysis (DGA) is one of the best known and most effective ways of monitoring the condition of power transformers. However, since transformers are rarely in thermal equilibrium, migration of characteristic-gases into insulating cellulose of transformers due to temperature variations causes error in dissolved gas analysis. This paper suggests a new diffusion dynamic model to explain the migration of ...


Condition based maintenance of power transformer: A case study

Ramesh Yadav; Santosh Kumar; A. Venkatasami; A. M. Lobo; A. M. Wagle 2008 International Conference on Condition Monitoring and Diagnosis, 2008

Power transformers are important and expensive components in electric energy networks. Unplanned outages of power transformers has a higher economical impact, which motivates, preventive tests and diagnosis for tapping the benefit of predicting condition to optimize maintenance and increase reliability of power system. Application of advanced diagnostic techniques for power transformers, provide the means to enhance the conventional maintenance program. ...


IEEE Draft Guide for Dissolved Gas Analysis in Transformer Load Tap Changers

PC57.139/D6, September 2015, 2015

General types of LTC mechanisms, breathing configurations, and electrical designs are described for reference for determining methods of testing and evaluating dissolved gases in mineral based transformer oils in Load Tap Changers (LTCs) are discussed and recommended in this guide. Measurements of dissolved gas concentrations in the LTC oil are required to implement this Guide. This guide is not manufacturer ...


Structural optimization by real-coded probabilistic model-building GA

T. Hiroyasu; M. Miki; H. Shimosaka; Y. Tanimura IEEE International Conference on Systems, Man and Cybernetics, 2002

In this paper, a probabilistic model-building genetic algorithm (PMBGA) is applied to structural optimization problems. PMBGA has high searching ability but it sometimes converges to the local minimum. To avoid this problem, the concept of distributed GA is applied to PMBGA. To deal with constraints, the penalty function and pulling back methods are also applied to PMBGA. Using the proposed ...


Failure statistics and power transformer condition evaluation by dissolved gas analysis technique

Thanapong Suwanasri; Ekkachai Chaidee; Cattareeya Adsoongnoen 2008 International Conference on Condition Monitoring and Diagnosis, 2008

Due to the degradation of power transformer under its normal and abnormal operating conditions, maintenance activities are vital to restore the condition. However, the preventive maintenance costs are now of primary concern. The scattering failure data are systematically recorded and analyzed to determine the critical component of power transformer. Two transformer models of rated voltage 115/22 kV and 230/115/22 kV ...

  • Substations

    This chapter discusses the major types of equipment found in most transmission and distribution substations. It describes the purpose, function, design characteristics and key properties. The substation equipment discussed in the chapter include: transformers, regulators, circuit breakers and reclosers, air disconnect switches, lightning arresters, electrical bus, capacitor banks, reactors, static VAR compensators and control building. Electric power systems have many ways to perform preventive maintenance. Scheduled maintenance programs, site inspections, routine data collection, and analysis are very effective. An enhanced or a more effective means of performing preventive maintenance is predictive maintenance. Sometimes this is called "condition based maintenance" where maintenance is based on measured or calculated need rather than just a schedule. Predictive maintenance can identify potential serious problems before they occur. Two very effective predictive maintenance programs or procedures are infrared scanning and dissolved gas analysis testing.
