Abstract: A system for measuring power quality on an electrical grid is disclosed. The system comprises a plurality of monitoring systems installed at a plurality of structures receiving power via the electrical grid, the structure being at the edge of the electrical grid and including, for example, houses and other buildings. Each monitoring system is configured to be electrically coupled to a panel assembly and an electric service meter at the structure at which it is installed. Each monitoring system also comprises a measurement unit configured to measure electrical values associated with the panel assembly at the structure and to detect power quality events based on the measured electrical values. The system further includes a reporting system communicatively coupled to the monitoring systems and configured to receive data representing the detected power quality events from the monitoring systems. The reporting system detects patterns of disruption within the electrical grid through pattern matching of detected power quality events received from the plurality of monitoring systems. The reporting system is configured to analyze the received power quality events and associated downloaded data to identify a probability of a complex event and to report this data to a user.

Abstract: An integrated meter in an electric vehicle supply equipment (EVSE) is described. Input power is received at input terminal of the EVSE and carried through a conductor that passes through an opening of a current transformer coil of the meter. The input power is split into a main path and an auxiliary path. The main path is for charging an electric vehicle (EV). The auxiliary path provides power to the meter to the EVSE itself. The auxiliary path passes through the opening of the current transformation coil in a reverse direction before being passed to a power supply of the meter and to a power supply of the EVSE to remove any current not for charging the EV from current measurements. The meter calculates energy measurements that do not include current drawn by the meter and the EVSE and transmits them to a processor of the EVSE.
