APPARATUS AND METHODS FOR TIMESTAMPING ELECTRICAL DATA IN A PANEL METER

摘要

An electrical panel meter system may include a controller and a plurality of meter modules. Each meter module may be configured to monitor, read, and store at the meter module electrical data related to electrical power provided to a respective branch circuit of the electrical panel meter system. The controller may be configured to issue a read command simultaneously to each meter module and to store a timestamp indicative of the issuance of the read command. The controller may also be configured to issue a send command sequentially to each meter module to transmit its stored electrical data reading. The controller may further be configured to append the stored timestamp to each received electrical data reading to create a timestamped electrical data reading suitable for use in power quality analyses. Methods of timestamping electrical data sampled in an electrical panel meter system are also provided, as are other aspects.

1. A method of timestamping electrical data sampled in an electrical panel meter system, the method comprising:
issuing a read command from a controller simultaneously to each one of a plurality of meter modules to read electrical data, the controller and the plurality of meter modules housed in an electrical panel enclosure; storing a timestamp indicative of the issuance of the read command; reading and storing at each one of the plurality of meter modules respective electrical data in response to receiving the read command; issuing a send command from the controller sequentially to each one of the plurality of meter modules to send their respective electrical data readings to the controller; receiving at the controller the respective electrical data readings from each one of the plurality of meter modules; and appending the stored timestamp to each of one the respective electrical data readings received at the controller to create respective timestamped electrical data readings.
