20 Claims

1. A method, comprising:

obtaining a configuration associated with at least one metering component installed at a site to be metered;

performing a metering component test including at least one of:

detecting phase assignment of the at least one metering component based at least on the configuration including by:

discharging a battery by a predefined power amount on a first line;

determining whether a measurement on a first metering component changed by an expected amount;

in response to a determination that the measurement on the first metering component did not change by the expected amount:

determining that a measurement on a second metering component changed by the expected amount;

determining that the second metering component is on the first line; and

setting a phase adjustment factor for the second metering component to reflect the determination that the second metering component is on the first line;

in response to a determination that the measurement on the first metering component changed by the expected amount:

determining that the first metering component is on the first line;

setting a phase adjustment factor for the first metering component to be 1;

discharging the battery by the predefined power amount on a second line;

determining whether the measurement on the second metering component changed by the expected amount;

in response to a determination that the measurement on the second metering component did not change by the expected amount and a determination that the measurement on the first metering component changed by the expected amount:

determining that the first metering component is on the second line; and

setting a phase adjustment factor for the first metering component to reflect the determination that the first metering component is on the second line;

in response to a determination that the measurement on the second metering component changed by the expected amount:

determining that the second metering component is on the second line; and

setting a phase adjustment factor for the second metering component to be 1; and

detecting polarity of the at least one metering component based at least on the configuration; and

outputting information associated with the metering component test.
