Joint Tutorial in Tokyo 28 September 2005

 

 

A-1: Statistical Analysis of Electrical Stress in Service

René Peter Paul Smeets and Anton L.J. Janssen, The Netherlands

 

The presentation will cover various aspects of electrical stresses on HV circuit breakers in service. Results will be presented of studies of relevant HV system and fault parameters collected with a world wide enquiry already in the nineties. New Japanese data will be added. Based on this information, methods will be presented to estimate the realistic electrical stresses in service, in terms of interrupted fault current and its statistical distribution. Conclusions will be drawn related to the need for a test program to cover these accumulated stresses, on top of the standard IEC certification tests.

A-6: Current Interruption using High Voltage Air-Break Disconnectors

David Peelo, Canada

 

The free-burning electric arc was studied quite intensely in the last part of the 19th century. The most famous of the early researchers was Hertha Ayrton who published her book "The Electric Arc" in 1902. The invention of the circuit breaker around 1904 dimmed interest in free-burning arcs and the subject languished except for some sporadic research in the first half of the 20th century. Utilities however have a vested interest in free-burning arcs because air-break disconnectors are used to interrupt currents of varying magnitude with actual practices being based more on trial-and-error than science. The tutorial describes research done over the past five years in Canada and The Netherlands and explains the behavior of free-burning arcs in air during the interruption of transformer magnetizing, capacitive and loop currents using disconnectors. Video images will be used extensively to illustrate the subject.

B-1: Substation Compaction

François Gallon, France and Tokio Yamagiwa, Japan

 

The presentation will cover the status of on-going analysis combining the possible introduction of lower standard insulation levels, together with the adequate protection provided by modern surge arresters suitably arranged, in an attempt to reduce the overall dimensions of AIS-type Substations. Benefits of these redesign practices can be extended in some cases to the voltage uprating of existing susbstations, making possible to exempt from the obligation to build a brand new switchyard. Information on alternative testing practices of equipment will also be commented.

B-2: SF6 Gas Handlings

Peter Glaubitz, Germany

 

Due to the high quality production standard of new electric power equipment regarding SF6 tightness, correct SF6 handling procedures are a very important topic to control and reduce the amount of SF6 released into the atmosphere.  The presentation reviews all significant aspects in handling SF6 gas used in electric power equipment during the whole life time. Among all, gas recovering, reclaiming and recycling have fundamental importance in order to keep the gas always in a closed cycle, avoiding any deliberate release and preserving the environment. State-of-the-art procedures, equipment, tools and instruments are described and suggested to minimize SF6 handling losses down to the minimum functional level for the equipment.  The safety issue as well as the personal protection equipment, instructions concerning storage and transportation as well as responsibilities are also given.  A functional description of state-of-the-art instruments and tools utilized for SF6 handling is also included.  Furthermore background information is given from the chemical-physical@characteristics of SF6, to the characteristics of the electric power equipment, from the environmental compatible SF6 policy to the gas categorization and from training of personnel to safety issues when operating with SF6 in a gas insulated substation.

 

ƒeƒLƒXƒg ƒ{ƒbƒNƒX:  Peter Glaubitz studied Electrical Engineering at Hanover Technical University graduating with honors in 1977. He then joined the production test field of the Siemens AG high voltage SF6-cb and switchgear factory, before moving to the commissioning department for high voltage SF6-switchgear and controlgear where he was engaged in various projects worldwide. During this period he was appointed to introduce and optimize SF6-handling procedures and SF6-handling equipment for SF6 switchgear. This was followed by international factory operations for SF6 switchgear and head office activities as advisor for SF6-switchgear projects and Regional Manager for high voltage SF6-switchgear projects. In 2001 he became Technical Director Production of the Siemens high voltage SF6-switchgear factory in Berlin.  Peter Glaubitz has continued in related roles focusing on SF6 switchgear policy and application.

"He is also active in IEC and DKE.

 

 

B-3: Substation Automation

Frank L. Baldinger, The Netherlands

 

The presentation will start with a short historical overview of substation architectures applied over the years. Over the years gained experiences have enabled the formation of an internationally accepted standard for internal substation communication between intelligent electronic devices applied in secondary system and the data model of the application describing the secondary functionality. The abstraction of the application model, the communication methodology and the possible architectures of the physical devices enable all kind of product solutions while the compatibility can be guaranteed.

Future implementation architectures will be discussed which enable significant cost savings despite of an enormous increase of functionality.
