The Laboratory of Metrology in Electrical Standards of Inmetro (Lampe) has built, in 2010, a transformer which is able to perform inductive voltage divider ratio calibrations using the bootstrap method. This transformer was idealized according to the design adopted at Physikalisch-Technische Bundesanstalt (PTB), and has very similiar characteristics to that system. Lampe's bootstrap system is not yet in operation, and DIT calibrations are presently being carried according to a triangular set of measurements involving standard capacitors. This method, though, has uncertanties limited to a few parts in 1E6; the primary objective of Lampe's bootstrap system project is to achieve uncertanties at least 10 times smaller than this.
