| 20100286954 | METHOD FOR DETERMINING LIGHTNING HAZARD DISTRIBUTION OF POWER NETWORK - A method for determining a lightning hazard distribution of a power network, includes: deriving a shielding failure lightning hazard distribution of the power network and a back flashover lightning hazard distribution of the power network from the number of ground lightning in each grid and ranges of hazardous currents, and deriving a historical lightning hazard distribution of the power network from a lightning faults database of the power network and the grids; and determining the lightning hazard distribution of the power network by integrating the shielding failure lightning hazard distribution of the power network, the back flashover lightning hazard distribution of the power network and the historical lightning hazard distribution of the power network. | 11-11-2010 |
| 20100076707 | CURRENT SENSOR FOR MEASURING INHOMOGENEITY OF POTENTIAL DISTRIBUTION OF ARRESTER - A current sensor for measuring the inhomogeneity of potential distribution of an arrester having a metal casing, a protection circuit of sampling resistor, a signal conditioning circuit, a signal acquisition circuit, an electro-optical conversion circuit, and a battery module. The signal acquisition circuit includes MSP430F149 micro controller unit having an A/D converter and a serial port. The current sensor is an active sensor, works in a high floating potential, and has a good real time response, high accuracy, low power consumption, good electromagnetic compatibility, and strong anti-interference capability even under harsh electromagnetic conditions. | 03-25-2010 |
