摘要： A system and method for developing, deploying and implementing computer applications for a power system has an open software framework for developing mobile applications. The mobile applications are developed by combining predefined modules having functionality to monitor a power system, change configuration settings within devices installed on the power system and allow utility personnel to quickly respond to events occurring on the power system.

摘要： An arc suppression circuit in a protection relay having trip contacts is used to turn off a battery-powered solenoid and trip an AC power circuit breaker. The arc suppression circuit uses a switch-control circuit to control the turning off of a semi-conductor switch so that the semi-conductor switch provides a current path around the trip contacts, and is carrying all, or substantially all, of the load current, before the trip contacts are opened. When the trip contacts begin to open, the switch-control circuit holds the semi-conductor switch on for a sufficient time to prevent an arc from becoming established before turning the semi-conductor switch off. In a second embodiment, the arc suppression circuit provides a second switch-control circuit. This second switch-control circuit is configured to accept control signals from a microprocessor within a protection relay. The microprocessor turns the semi-conductor switch on before the contacts begin to open, thereby providing a current path around the contacts before the contacts begin to open. The microprocessor turns the semi-conductor switch off after a time sufficient to prevent an arc from becoming established.
