Managing the determination of a transfer function of a measurement sensor

An electrical measurement system for measuring at least one electrical property, the electrical measurement system comprising:

• a first measurement sensor for measuring a first electrical property;
• a first module configured to operate in one of a plurality of operating states comprising:
• a) a first operating state to monitor at least the first measurement sensor to determine a first monitor result comprising:
• 1) an estimate of a transfer function of the first measurement sensor, and
• 2) a corresponding certainty value indicative of the accuracy of the estimate of the transfer function of the first measurement sensor,
• b) a second operating state in which no measurement sensor of the electrical measurement system is monitored, and
• a a second module configured to:
• using the first operating state, measure the first electrical property of a utility meter to determine the first monitor result;
• select one of the plurality of operating states wherein the selection is from a group consisting of the first monitor result an utilization target based on the one or more previously determined certainty values, wherein the first utilization target is indicative of a target total proportion portion of the first monitoring time window to be spent by the monitor module determining monitor results relating to the first measurement sensor;
• and
• perform a control action for controlling the operation to implement the selected operating state.

A method of controlling an electrical measurement system, the method comprising:

• including a plurality of operating states comprising:
• a) a first operating state to monitor at least a first measurement sensor for measuring a first electrical property of the electrical measurement system to determine a first monitor result comprising:
• 1) an estimate of a transfer function of the first measurement sensor, and
• 2) a corresponding certainty value indicative of the accuracy of the estimate of the transfer function of the first measurement sensor,
• b) a second operating state in which no measurement sensor of the electrical measurement system is monitored;
• using the first operating state, measure the first electrical property of a utility meter to determine the first monitor result;
• selecting one of the plurality of operating states, wherein the selection is based at least in part on at least one of the first monitor result or the corresponding certainty value or a utilization target based on the one or more previously determined certainty values, wherein the first utilization target is indicative of a target total proportion portion of the first monitoring time window to be spent by the monitor module determining. monitor results relating to the first measurement sensor;
• and
• performing a control action for controlling the operation to implement the selected operating state.
