An improved Mayr-type arc model based on current-zero measurements circuit breakers

In this paper, it is shown that the Mayr-type arc models can be used to describe circuit breaker arc behavior before current zero exactly. Based on this analysis, the different types of `modified' Mayr arc models can be explained. As a result of the theory, an improved Mayr-type arc model-with...

Description
Summary:In this paper, it is shown that the Mayr-type arc models can be used to describe circuit breaker arc behavior before current zero exactly. Based on this analysis, the different types of `modified' Mayr arc models can be explained. As a result of the theory, an improved Mayr-type arc model-with a constant time parameter and a cooling power which is dependent on the electrical power input-is introduced and used to reproduce current zero measurements successfully
