Abstract

The present invention provides systems and methods for testing and storage of information related to a component. A data collection device having a memory is fixedly connected to the component. A test device communicates with the data collection device to store test data concerning the component in the data collection device. The test device also performs analysis of the test data and provides information concerning the health and maintenance history of the component. The present invention also provides systems and methods for determining the current drawn or supplied by electrical components connected in parallel in an electrical system. A current sensor located between the electrical components determines the current supply or draw of one of the electrical components, while a current sensor between the electrical components and the remainder of the electrical system determine a cumulative current draw or supply by both the electrical components.
