        Automatic control is a reality.

        Supervisory control has been introduced.

        The inter - connection of systems is no longer an experiment.

        Service is now reliable and continuous.

All of these are attributes of super-power— a new era in the electrical industry. And they were made possible through Westinghouse pioneering in the relay art. Not only has Westinghouse introduced most of the present-day relays, but this Company has also developed various schemes and methods of relay application.

Westinghouse relays and relay practice have played an important role in the progress of the electrical industry. It is the purpose of Westinghouse to maintain and extend this leadership to meet the exacting requirements of the future.
