Insertion Resistance

A typical Pearson Current Monitor contains a distributed load resistance. When using such a current transformer this resistance appears as a very small equivalent series resistance in the circuit being measured. This resistance is usually so small it can be neglected. For those cases when it needs to be considered, the values are tabulated here.
