3rd International Colloquium "Transformer Research and Asset Management"
1. „Resonance and Feroresonance in Power Network“
Chief Power Systems Engineer
The tutorial will provide an overview of the fundamental frequency resonance and ferroresonance in power networks starting with a detailed description. It will then covers various network topologies that may lead to each phenomenon. Particular attention will be given to shunt compensated transmission lines that can result in resonance. Ferroresonance in electromagnetic voltage transformers and power transformers will be treated separately and in great depth. Mitigation measures to overcome resonance and ferroresonance, guidance in modelling both phenomena and case studies will also be provided.
2. „Transformer Procurement Process“
TB TCS Ltd
Decisions made in the procurement process define the future reliability and expected life of a transformer. CIGRE has produced a number of guides under the umbrella of WG A2-36 -Transformer Procurement Process –to support users in terms of specification, design review and the assessment of the capability of a manufacturer. This tutorial is intended to make the recipient aware of the issues that need to be addressed during the procurement process and guide the user towards the support provided in the guides.
