20120319692 | MOBILE SYSTEM FOR MEASURING ABNORMALITY DETECTION PARAMETERS OF A SWITCH IN A HIGH VOLTAGE ELECTRICAL SUBSTATION - There is provided a method for measuring abnormality detection parameters of a disconnect switch, comprising: releasably connecting a first sensor to the disconnect switch, the first sensor adapted to measure a first parameter related to a position of an arm of the disconnect switch, the disconnect switch comprising a rotating actuation element operatively connected to the arm for moving the arm between a closed position and an open position; releasably connecting a second sensor to the rotating actuation element, the second sensor adapted to measure a second parameter related to a torque of the rotating actuation element; moving the arm using the actuation element; measuring and storing in memory the first and second parameters while the arm is moving; and disconnecting the first and second sensors | 2012-12-20 |
20120319693 | ELECTRIC POWER STORAGE SYSTEM - When a continuous short circuit occurs between both terminals of a battery pack, fault, destruction and rupture of the battery can occur. Further, when a momentary short circuit occurs, a user may continue to use, without knowing thermal and electrical damage to the batteries, and reliability for the batteries is impaired, To overcome the problem, in a battery pack configured by connecting a plurality of storage batteries in series, at least one first storage battery is included which has a low capacity compared to second storage batteries during high-rate discharge, and the first storage battery undergoes polarity inversion during external short circuit, thereby preventing the other batteries from becoming damaged. There are also included a detector that detects voltage of the first storage battery, and a fault signal generator that generates an output fault signal when a voltage detected by the detector inverses. | 2012-12-20 |
20120319694 | Circuit System and Method of Controlling Power Management - A circuit system is disclosed. The system comprises a master circuitry, at least one slave circuitry which has a battery sensor for checking battery status of a power supply battery and a shut down mechanism for controlled shut down upon detection of low battery by the battery sensor, and a battery sensor manipulation circuit controlled by the master circuitry. The battery sensor manipulation circuit is arranged to manipulate sensed battery status for the battery sensor of at least one of the at least one slave circuitry to force the controlled shut down of the at least one of the at least one slave circuitry upon provision of a shut down control signal from the master circuitry. A method of controlling power management of such a circuit system is also disclosed. | 2012-12-20 |
