- Westinghouse Transformer, 1889-1900 - Transformers increase or decrease voltage and are essential to alternating current (AC) power systems. In the late 1800s, with the help of transformers, AC power systems proved more efficient and economical than their direct current competitors. Transformers helped convert electricity to high voltage for transmission across long distances, then reduced it to lower, safer voltages for use in homes and factories.

- Westinghouse Shallenberger Ampere-hour Meter, 1888-1890 - Oliver B. Shallenberger, chief electrician at Westinghouse, invented the first successful AC ampere-hour meter in 1888. This meter measures the flow of electric current through a circuit. Early meters like this helped companies that supplied electricity to customers monitor usage and charge appropriate rates. Shallenberger's meter also paved the way for the acceptance of AC power distribution.
