| 20110254564 | System and Method for Detecting Voltage Dependence in Insulation Systems Based on Harmonic Analysis - A method of testing an insulation system is disclosed. The method comprises coupling a first test lead to a first conductor, the first conductor at least partly isolated by the insulation system and coupling a second test lead to a second conductor or a ground. The method further comprises applying a test signal to the first test lead, receiving a test response from the second test lead, and analyzing the test response from the second test lead to determine a harmonic content of the test response. The method further comprises, when the harmonic content is equal to or greater than a predetermined threshold, determining that the insulator system has non-linear properties. | 10-20-2011 |
| 20100106435 | System and Method for Power System Parameter Measurement - A system and method of testing a power system component is disclosed. The system and method comprises coupling a test set to the power system component and stimulating the power system component with a frequency sweep signal. The method also comprises capturing a response of the power system component to the frequency sweep signal, wherein the response relates to frequency and mapping the response to an estimated response, wherein the estimated response relates to temperature. The method also comprises evaluating the power system component based on the estimated response. | 04-29-2010 |
| 20100026312 | System and Method for Power System Component Testing - A method of testing a power system component is disclosed. The method comprises coupling a test set to the power system component and displaying a test form on a display integral with the test set. The method also comprises inputting at least a first test control parameter into the test form using an interface integral with the test set. The method also comprises stimulating the power system component using the test set to produce a first response of the power system component, wherein the stimulating is performed based at least in part on the first test control parameter. The method also comprises displaying a first test result in the test form on the display, wherein the first test result is based on the first response. | 02-04-2010 |
| 20090273336 | Upgradable Test Set - An upgradeable test set is that includes a stimulator circuit to transmit test signals to an electrical equipment under test, a coupling to removeably couple at least the stimulator circuit to one of a plurality of front-end interfaces. The plurality of front-end interfaces include a first front-end interface having a first display and a first input device and a second front-end interface having a second display and a second input device. The first display and the second display have different display characteristics, and the first input device and the second input device have different characteristics. The one of the front-end interfaces communicates a test control parameter to the stimulator circuit and a response of the electrical equipment under test is communicated to the one of the front-end interfaces. The case is configured to enclose the stimulator circuit, the one of the front-end interfaces, and the coupling. | 11-05-2009 |
