| Popis: | Although their primary purpose is not line discharging, inductive voltage and combined transformers are recognized as suitable solution for line discharge due to a typically very fast decay of trapped charge. Discharge capability of instrument transformers is not defined by relevant standards. Instead, it is often specifically defined by technical specifications of individual network utilities. In this paper authors have analysed discharge capability of inductive voltage and combined transformers. The focus of this paper will be placed on two main aspects of line discharge activity: thermal and mechanical capability. The aim of this document is to prove that discharge capability of inductive and combined transformers can be simulated with adequate precision. Furthermore, the proposed approach provides an indispensable tool for determining and optimizing relevant electrical and mechanical transformer parameters in order to achieve requested discharge capability even when technical specifications or project requirements exceed discharge capability of a standard instrument transformer design. Lastly, the paper will present relevant testing procedures, which verify discharge capability of inductive voltage and combined transformers. |
