An automated data transmission system for communicating warning signals and other information directly to law enforcement or security personnel in order to reduce response times. In the disclosed embodiment of the invention, sensing circuitry is added to a standard security system installed at an industrial or residential site. The sensing circuitry detects activation of the security system by sensing an outgoing warning call. Following activation of the security system, an automatic dialer or other automated transmitter circuitry is used to initiate a call to a processing computer at a predetermined phone number. The processing computer utilizes Caller ID.TM. information to determine the phone number assigned to the automatic dialer. The processing computer also maintains a database that associates assorted pieces of information with each phone number in the list, including the key map code location of the business, address of the protected business, name, date and time, and the phone number of a company contact. This information is communicated, through a paging service provider, to a dedicated group of one or more alphanumeric paging devices. The group of dedicated paging devices is provided to the law enforcement personnel assigned to protect the geographic region in which the secured industrial or residential site is located. Time-consuming human involvement in the notification process is thereby eliminated.

A voltage estimator for a generating system having a DC link and an inverter detects the magnitudes of the voltage and current on the DC link and develops an estimate signal representing the estimated magnitude of a fundamental component of output voltage developed by the inverter from the sensed DC voltage and current magnitudes.
