An external current transformer is available as an option, see Figure 1. The
transformer has a transformation ratio between 80 and 1200:1 for the measurement of a
single branch in mesh-operated earthing systems. This enables the user to measure on
high voltage pylons without separating the overhead earth wires or earth strips at the
bottom of the pylons. It is also used to measure lightning protection systems without
separating the individual lightning protection wires.
