Abstract: Disclosed herein are a variety of systems and methods for entry of data relating to an electrical power delivery system using a web-based interface. One embodiment may include a computer program product having a client-side module to communicate with a server-side module. The client-side module may further include a web browser interface module to retrieve data entered by an operator into a data entry field in a web browser, a user interface module to display variable length data to a user via the web browser, and a communication module to manage communication with the server-side module. The communication module may further be configured to generate an object comprising data entered by the user into the web browser, transmit the object to the server, and receive a response from the server.

Abstract: The heat sink assembly includes a heat sink member with a body portion and an upper mounting portion. The heat sink member is connected to an integrated circuit on a printed circuit board assembly. A resilient mounting assembly is positioned on the mounting portion of the heat sink assembly and is constructed and arranged to permit the heat sink assembly to be removably mounted on the mounting member, which in turn is attachable to or part of the chassis of the electronic equipment. The mounting assembly includes a bias element, such as a spring, for holding the heat sink assembly and the mounting member together in a low thermal resistance relationship.

Abstract: The protective relay for an induction motor includes a first program function which establishes a first thermal threshold value for a start condition of the motor, using a start condition thermal model. The thermal condition of the motor is determined by measuring the motor's thermal response to stimulus. A comparator compares the start condition thermal representation with the first thermal threshold value and monitors whether the first thermal threshold value is exceeded by the start condition thermal representation. A second thermal threshold value is established for a run condition of the motor, including a selected time constant which results in the time-current curves of the start and run conditions being substantially continuous. A representation of the thermal condition of the motor is then developed in response to stimulus current. A comparator then compares the run condition thermal representation with the second thermal threshold value.
