  • Protection system for an electric meter
    Patent number: 11513144
    Abstract: A protection system described herein includes a first connector, a second connector, and a voltage-limiter device. The first connector is configured to connect to a first load-side terminal of an electric meter, and the second connector is configured to connect to a second load-side terminal of the electric meter. In a circuit between the first connector and the second connector, the voltage-limiter device is configured to clamp a voltage between the first and second load-side terminals at a trigger voltage, to prevent a greater voltage from reaching the electric meter when a service-disconnect switch of the electric meter is open and an external voltage greater than the trigger voltage is applied to a load side of the electric meter. The voltage-limiter device provides a conductive path in parallel with a customer premises associated with the electric meter when the voltage between first and second connectors reaches the trigger voltage.
