IN3-Information Note_ Toroids compatible with Vigilohm Fault locators.pdf - Box

In addition, the following excel document can help to define the diameter of toroid requested to monitor a feeder:

IN3- Selection of Toroid depending on cables diameter.xls - Box

>>> The criteria of selection is that Diameter of toroid > 1,4 x Diameter of cables bundle

Criterias such as maximum cross section area of conductors; maximum admissible current... do not apply to Vigilohm, since we measure differential currents (these criterias only apply if the toroids are used with Vigirex devices)

NB: A version in french of this document is available here.
