    摘要： Systems, devices, and methods for a transformer including: a first drive winding (206) wound on a first core; a second drive winding wound on a second core; a sense winding wound across the first and second cores; and a compensation winding wound across the first and second cores; where one or more utility lines are threaded through a middle of the first and second cores, a common mode current in the one or more utility lines causes one or more pulses to appear on the sense winding, a current on the compensation winding is adjusted until the one or more pulses on the sense winding are cancelled out, and the common mode current on the one or more utility lines is the adjusted current on the compensation winding multiplied by a turn ratio between the compensation winding and the sense winding.

    摘要： An electric vehicle (EV) charger restart method includes determining a respective restart delay time (Tdel) for each of one or more electric vehicle chargers, each respective restart delay time (Tdel) comprising a respective delay time increment based on a generated random number and a group time interval for reset (Tint) (block 212), and initiating a restart of at least one of the one or more electric vehicle chargers, if an existing time (Tnow) is greater than an established time line start time (TPOK) plus Tdel.

    摘要翻译： 一种电动车辆（EV）充电器重启方法，包括为一个或多个电动车辆充电器中的每一个确定相应的重启延迟时间（Tdel），每个重新启动延迟时间（Tdel）包括基于生成的随机数的相应的延迟时间增量，以及 如果现有时间（Tnow）大于建立的时间线开始时间（TPOK），则重新组合时间间隔（Tint）（框212），并且启动一个或多个电动车辆充电器中的至少一个的重启， 加Tdel。
