Device and method of installing capacitors on a utility company's power meter
View Patent ↗The Invention relates to the field of power factor correction in general. Specifically, the Invention comprises a device for insertion between the power meter of an electrical utility supply and the load which is further comprised of an electrical capacitance that is sized by the method of the Invention to improve the electrical power factor of the system as measured at the meter. The benefits of the Invention include increased power factor, lower power consumption, lower energy costs, and ease of installation due to its novel plug-in packaging approach wherein a utility meter adapter embodiment of the present invention containing power factor correcting circuit capacitor(s) plugs between a utility meter and its meter socket. The device of the invention installs between the power meter and power meter receptacle without requiring significant effort or time for installation.
1. A power factor correcting utility meter socket adapter, comprising:
a round cylindrical body sized to fit a standard utility power meter, and having top and bottom flanges for retainers to secure the adapter to said utility power meter and a service panel;
a set of socket jaws comprising a first socket jaw and a second socket jaw in a topside of the body for connection to said utility power meter, and a corresponding set of jaw blades in a bottom of the body for connection to said service panel; and
a power factor correcting circuit element having a first terminal and a second terminal and being mounted inside of the round cylindrical body, and wherein said first terminal is electrically connected to said first socket jaw, and wherein said second terminal is electrically connected to said second socket jaw.
2. The adapter of claim 1 , wherein the power factor correcting circuit element is a capacitor.
3. The adapter of claim 2 , further comprising a first over current protection circuit element having a first terminal and a second terminal, wherein said over current protection device is electrically in series with said first terminal of said capacitor and said first socket jaw.
4. The adapter of claim 3 , further comprising a second over current protection circuit element having a first terminal and a second terminal, wherein said over current protection device is electrically in series with said second terminal of said capacitor and said second socket jaw.
5. The adapter of claim 1 , wherein the power factor correcting circuit element is a plurality of capacitors.
6. The adapter of claim 5 , further comprising a first over current protection circuit element having a first terminal and a second terminal, wherein said over current protection device is electrically in series with said first terminal of said plurality of capacitors and said first socket jaw.
7. The adapter of claim 6 , further comprising a second over current protection circuit element having a first terminal and a second terminal, wherein said over current protection device is electrically in series with said second terminal of said plurality of capacitors and said second socket jaw.
8. The adapter of claim 1 , further comprising a first over current protection circuit element having a first terminal and a second terminal, wherein said over current protection device is electrically in series with said first terminal of said power factor correcting circuit element and said first socket jaw.
9. The adapter of claim 8 , further comprising a second over current protection circuit element having a first terminal and a second terminal, wherein said over current protection device is electrically in series with said second terminal of said power factor correcting circuit element and said second socket jaw.
