| A current transformer is a type of electrical | | | | basic items that are reasons for the burden |

| extensively and is typically defined by its | | | | distance from meter which can be overcome by |
| current ratio from primary to secondary. | | | | using current transformer with 1 amp which |
| Current transformers (Current Transformer) | | | | produce low voltage drop. The Rating factor |
| are the most commonly used in metering and | | | | of a Current Transformer which is dependent |

| industry where they facilitate the safest | | | | determine the absolute maximum measurable |
| requirement of a huge currents, often in the | | | | primary current by multiplying the full load |
