System for measuring contact force in a utility meter
View Patent ↗The present disclosure relates to a system and method for evaluating the adequacy of a connection between a utility line and a utility meter. In one embodiment, a force sensing unit is disposed between a first half and a second half of a first terminal of the utility meter and is configured to measure a contact force between the first terminal and a socket jaw.
1. A system configured to measure an amount of electricity being consumed by a load, comprising:
a utility meter comprising a first terminal, wherein the first terminal comprises a first half and a second half;
a socket jaw, comprising:
a first blade;
a second blade, wherein the first blade and the second blade are configured to receive the first terminal;
a force sensing unit disposed between the first half and the second half of the first terminal, wherein the force sensing unit is configured to measure a contact force between the first blade and the first terminal; and,
a service switch configured to disconnect a flow of electricity through the utility meter when the contact force is less than a predetermined value.
2. The system of claim 1 , wherein the predetermined value is approximately 225 Newtons (“N”).
3. The system of claim 1 , wherein the force sensing unit comprises a piezoresistive force sensor.
4. The system of claim 1 wherein the service switch is a relay.
