What does the following CT ratio feeding an 87T Differential Relay mean? 600/100-5 Do I use the 600 or the 100 as the primary ratio? |

600/100-5 Do I use the 600 or the 100 as the primary ratio? How many leads are coming out of the secondary? It may be a multi-ratio CT. MR 600/5 conn 100/5. |

This is generally what the underlining means. |

Thanks guys for the info. After some digging I found that it was a Multi-Ratio (MR) CT with the 100 lead selected. |
