    • The invention is a device and method for eliminating core excitation losses in a distribution transformer when the transformer is not supplying power to loads. The invention consists of sensors, a control circuit, a user interface and a power contactor. The power contactor is connected on the line side of a transformer and is opened or closed automatically based on preprogrammed time or load criteria determined by the control circuit. In one operational mode and when the transformer is disconnected from the line, the control board generates low power pulses at the transformer load connection points in order to “search” for loads. If a load is detected, the transformer is reconnected by way of contactor closure. If the transformer load drops to zero, for a predetermined amount of time, the transformer is again disconnected and the pulsed load search is reestablished.
    • 本发明是一种用于在变压器不向负载供电时消除配电变压器中的磁芯励磁损耗的装置和方法。 本发明由传感器,控制电路,用户接口和电力接触器组成。 电源接触器连接在变压器的线路侧,并根据由控制电路确定的预编程时间或负载标准自动打开或关闭。 在一种操作模式下,当变压器与线路断开时,控制板在变压器负载连接点产生低功率脉冲,以便“搜索”负载。 如果检测到负载,变压器通过接触器闭合重新连接。 如果变压器负载下降到零,在预定的时间内,变压器再次断开并且重新建立脉冲负载搜索。
