( 1 ) Program of the course "DESIGN of SWITCHGEAR, SWITCHBOARDS, BUSDUCTS & SUBSTATIONS with software SwitchgearDesign"

›› ( 1 )
In this video are shown the topics of the complete course whose parts can be obtained, separately, in the list below.
The training focuses on professionals working as manufacturers of equipment for high and low voltage substations as well as experts working in certification of companies and testing laboratories.
Participants can review the engineering concepts required to produce a good design. Receive and learn to use the software SwitchgearDesign developed by Sergio Feitoza, presenting the training.
The software allows developing equipment through the simulation of the main high-power testing, before going to a testing laboratory to do the type test.
Beyond the use of the software, the training bring to the participants solid engineering concepts to enable them to solve daily problems. The full program includes:
1-SPECIFICATION OF CURRENTS AND VOLTAGES.
• Load flow and definition of the normal currents.
• Short circuit studies (currents and durations)
• Basic concepts of the “free” software ATP / ATPDRAW
2 - OVERVOLTAGES AND INSULATION COORDINATION.
• Transients and insulation coordination.
• Techniques to reduce over voltages (synchronizers, pre insertion resistors, surge arresters)
• Levels of industrial frequency and impulse withstand voltages
• Aspects of electric fields and distances in installations
• Dielectric tests (impulse, AC voltage, corona, RIV, …)
3. SHORT CIRCUITS, AMPACITIES, OVERLOADS
• Electrical contacts and temperature rise
• Reduction of lifetime, supportability of materials to temperatures
• Ventilation and contact resistances
• Overloads in power transformers
• Temperature rise tests
• Electrodynamic forces during short circuits
• Magnetic induction
• Calculation of the forces and mechanical stresses.
• Limit values for insulators and busbar conductors.
• Short-time withstand current & peak current
• 3.3.6 – Some aspects of magnetic fields in installations
3 -TRANSIENT RECOVERY VOLTAGES AND INTERRUPTION PROCESSES
• Circuit breakers, switches, their technologies
• Expulsion type and current limiting fuses
• Breaking Tests
4 –POWER ARCS AND SAFETY
• Internal arc in switchgear (medium and low voltage).
• Technologies to control the effects of arc a
• Aspects of explosions and fires in transformers.
• Arcs in insulators strings and tests
5 – TECHNICAL STANDARDS FOR SWITCHGEAR
• IEC 62271-200 (medium voltage)
• IEC 61439 and IEC 60439 (low voltage)
• Planning the use of design rules of IEC 61439.
• IEC 62271-307 - Parte 307: extension of the validity of Type test reports.
• IEC 62271-1 (common clauses), IEC 62271-100 (circuit breakers), IEC 60282-2 (expulsion fuses), IEC 60076 (Power transformers).
6 TECHNICAL SPECIFICATIONS FOR T&D EQUIPMENT
• The most efficient specification is the IEC Standard
• High voltage switches and isolators
• Circuit - breakers
• Surge arresters
• Power transformers and reactors
7 SOFTWARE SWITCHGEAR_DESIGN (Case Studies)
• State of the art of the use of simulations to replace some laboratory tests
• Simulation of short-time withstand current and peak tests (calculation of electro dynamical forces, mechanical stresses )
• Simulation of temperature rise / heating tests (calculations and how to optimize the design)
• Simulation of internal arc tests (overpressures, burn-through and supportability)
• Case studies with the software ( LV and MV switchgear)
• Mapping of electromagnetic fields
