Patent number: 9921252Abstract: The isolation resistance value is determined by measuring the voltage across a set of high resistance resistor networks placed between the high voltage battery pack (both the positive and negative terminals) and the chassis ground and then modifying the resistance networks by switching in an additional high resistance network and repeating the measurements. This results in a system that can be assembled using low cost components to determine with a high degree of accuracy the value of the isolation resistance.

Patent number: 8988234Abstract: An alarm system for alarming whenever there is a power leakage from an electronic device, includes a voltage decreasing circuit, a switch circuit and an alarm circuit. The voltage decreasing circuit receives a first voltage from a live wire output terminal and outputs a second voltage. The switch circuit outputs a control signal when the power leakage is detected. The switch circuit is electrically connected to a connection port. The connection port is electrically connected to the live wire output terminal and a neutral wire output terminal. The alarm circuit receives the control signal and alarms. If there is power leakage from the electronic device, the first voltage from the live wire input terminal flows into the ground wire input terminal via the electronic device; the switch circuit turns on and the alarm circuit is closed to alarm.Type: GrantFiled: July 29, 2011Date of Patent: March 24, 2015Assignee: Zhongshan Innocloud Intellectual Property Services Co., Ltd.Inventor: Ke-You Hu

Patent number: 8866485Abstract: An electrical circuit tester includes a first testing device and a second testing device provided in a hand-held housing, each being electrically isolated from the other. Multiple light sources are electrically coupled to one of the first and second testing devices to provide a visual indication of the testing result. The first testing device includes a conventional three-prong plug extending out from the surface of the housing and configured to be inserted into a standard electrical receptacle. The second testing device includes one or more keyed cavities, each being designed to receive all or a portion of a plug into the cavity in only one orientation. Each cavity can include at least one blade prong that makes electrical contact with the plug when inserted into the cavity. Both the first and second testing devices can be operated simultaneously with separate sets of light sources providing separate testing indications for each.Type: GrantFiled: October 3, 2011Date of Patent: October 21, 2014Assignee: Cooper Technologies CompanyInventors: Darron Kirby Lacey, Qi Hui, Erik Jeffrey Gouhl, Carlos Eduardo Restrepo
