| 摘要 |
A system for measuring the electrical quantities in each phase of a medium, high or very high voltage overhead or cabled electrical line, said electrical quantities being the current and/or voltage of said phase, said system comprising means (10), cooperating with said phase, for measuring each electrical quantity, and transfer means (11) to transfer each measurement datum to a control station for the electrical line; the measurement means (10) are associated with a coupling capacitor (1) comprising an internal capacitor (8) to which each measurement datum is transferred, said measurement means being powered via the internal capacitor, the measurement data being sent to the base of said coupling capacitor. |
