<p>A local or remote distribution management system, especially an auto-metering unit applied to a distribution transformer, comprises a suspending power supply(1), a high voltage capacitance divider(2), a current transformer(5), a wireless transmission unit(4) and a metering unit(3),which are provided in the primary winding(6) of the transformer, and a power transformer(22), a current transformer(21), a transformer parameter monitoring unit(24) and a metering unit(28),which are provided in the secondary winding(29) of the transformer. By metering the primary winding of the transformer and by utilizing the secondary winding metering realized bythe auto-metering unit, so that the loss of the transformer can be calculated.</p> |
