Systems for electrically connecting metering devices and distributed energy resource devices
A meter collar includes a connection path to form an electrical connection between a distributed energy resource (DER) meter and line voltage wirings of an electric distribution system and a second connection path to form an electrical connection between the DER meter and neutral wires of the electric distribution system, a DER device, and a load. Further, the meter collar includes a third connection path within the meter collar to form an electrical connection between the DER meter and output voltage wirings of the DER device. Furthermore, the meter collar includes mating connectors electrically connected to a first end of a corresponding connection path to accept mating connectors of the DER meter. The meter collar also includes mating connectors electrically connected to a second end of the corresponding connection path to mate with the line voltage wirings, the neutral wires, and the output voltage wirings.
ELECTRIC METER COLLAR HOUSING ELECTRIC VEHICLE SUPPLY EQUIPMENT
An electric meter collar housing an electric vehicle supply equipment (EVSE) therewith. The collar is configured to be located between the electric meter receptacle and the electric meter. The collar includes a fused disconnect, a controller, an EV connector inlet, a relay, a ground fault circuit interrupter (GFCI) current transformer, and first and second current transformers. The fused disconnect provides an external switch and external fuses. The EV connector inlet has a plurality of insulated receptacles to receive pins of an untethered EV cable. The relay is coupled between the fused disconnect and the EV connector inlet and is controlled by the controller. The GFCI current transformer is coupled between the relay and the EV connector inlet to detect ground faults during EV charging. The first and the second current transformers are to measure current utilized during EV charging.
ENERGY METERING AND SURGE CURRENT DETECTION
A circuit is provided for energy metering and surge current detection. It uses a current transformer. A first current sensing arrangement is connected to the secondary side of the transformer for energy metering and a second current sensing arrangement is connected to the secondary side, with a high pass filter, for surge current detection. A single component is thus able to provide energy metering and surge detection.
