Distribution Line Clamp Force Using DC Bias on Coil |
摘要 |
A power distribution monitoring system is provided that can include a number of features. The system can include a plurality of monitoring devices configured to attach to individual conductors on a power grid distribution network. In some embodiments, a monitoring device is disposed on each conductor of a three-phase network and utilizes a split-core transformer to harvest energy from the conductors. The monitoring devices can be configured to harvest energy from the AC power grid and apply a DC bias to core halves of the split-core transformer to maintain a positive magnetic force between the core halves. Methods of installing and using the monitoring devices are also provided. |

1. A method of monitoring a power grid distribution network, comprising the steps of:
harvesting energy from a conductor line of the power grid distribution network with a split-core transformer of a monitoring device installed on the conductor line; powering the monitoring device with the harvested energy; and applying a DC bias to the split-core transformer with a circuit of the monitoring device to eliminate periodic separation between first and second core halves of the split-core transformer. |
