Best Answer

The K Factor in Current Transformer Metering is the Multiplyer. The current Transformers might be a winding ratio of 200/5 therefore the K Factor would be 40. Meaning for every 100Amps in the meterered conductors only 2.5A is read by the meter the resultant reading is then multiplied by 40 to give the reading of 100A (or the calculated kWh reading for electricity consumption)
