Open the CIPO recordAbstract From the Canadian patent
The invention relates to a method for regulating the voltage at which electric energy is supplied at the delivery points in a network for distributing electricity. The voltage of electric energy supplied through a high-voltage network is reduced to a voltage suitable for a mediumvoltage network by means of at least one variable transformer. The voltage of the electric energy in the medium-voltage network is reduced by means of at least one transformer, to a voltage suitable for a lowvoltage network supplying the electric energy to the consumers. The adjustment of the variable transformer between a high-voltage network and a medium-voltage network is influenced by the actual voltage measured …

Why it's free to use
- Filed April 29, 1993. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended April 29, 2013.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by April 29, 2015.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
