Hi i'm currently studying for my city and guilds electrical course and am stuck on this question.
i think i understand that the Zs of 0.19 means the time it takes for the breaker to trip but could somebody explain what this means in lehmans terms.
The actual question redas
Explain the relevance of the information which states the the Zs of the installation is 0.19 and a PFC of 1.2ka.
