Abstract
An automatic power line monitor system is disclosed for use in monitoring the electrical voltage supplied to an electrical system or appliance by monitoring the supplied electrical voltage and preventing the supplied electrical voltage from reaching the electrical system or appliance when the supplied electrical voltage is not within a predetermined range and for automatically restoring the supplied electrical voltage to the electrical system or appliance when the supplied electrical voltage is within the predetermined range.
Claims23
A power line monitor system for use with a recreational vehicle for connecting the electrical system of such recreational vehicle to a source of electrical power, comprising:
- means for connecting said power line monitor system to said source of electrical power;
- means for connecting said electrical system of said recreational vehicle to said power line monitor system;
- means for monitoring said source of electrical power to determine whether voltage supplied by said source of electrical power is within a predetermined voltage range;
- means for indicating electrical power outside of said predetermined voltage range including at least one indicating means connected to indicate a condition wherein the voltage is at least one of higher and lower than said predetermined voltage range, and wherein, during said condition wherein the voltage is at least one of higher and lower than said predetermined voltage range, said at least one indicating means is enabled prior to interruption of said electrical system and disabled prior to restoration of said connection of said recreational vehicle to said source of electrical power;
- and
- means for interrupting connection of the electrical system of said recreational vehicle to said source of electrical power while said voltage supplied by said source of electrical power is outside of said predetermined voltage range and for automatically restoring connection to said electrical system of said recreational vehicle when said voltage is within said predetermined voltage range, said means for interrupting including at least two switching means, wherein a first switching means controls a second switching means for interrupting and automatically restoring connection of said electrical power to said electrical system of said recreational vehicle.

A method for monitoring the value of the electrical voltage supplied to the electrical system of a transportation vehicle from an outside source of electrical power for preventing damage to the electrical system of the transportation vehicle, comprising the steps of:
- connecting means for monitoring the value of the electrical voltage supplied to the electrical system of a transportation vehicle from said outside source of electrical power between said electrical system of said transportation vehicle and said outside source of electrical power;
- monitoring the value of said electrical voltage supplied to the electrical system of said transportation vehicle by said outside source of electrical power to determine when said value is outside of a predetermined voltage range of values;
- indicating when said electrical voltage is outside of said predetermined voltage range utilizing at least one indicating means connected to indicate a condition wherein the voltage is at least one of higher and lower than said predetermined voltage range, and wherein, during said condition wherein the voltage is at least one of higher and lower than said predetermined voltage range, said at least one indicating means is enabled prior to preventing said electrical power from reaching the electrical system of said transportation vehicle and disabled prior to restoring said electrical power from said outside power source to said electrical system of said transportation vehicle;
- and
- preventing electrical power from said outside source of electrical power from reaching the electrical system of said transportation vehicle while said value of said electrical voltage supplied by said outside source of electrical power is outside of said predetermined voltage range and automatically restoring electrical power from said outside source of electrical power to said electrical system of said transportation vehicle when said value of said electrical voltage is within said predetermined voltage range, said step of preventing utilizing at least two switching means, wherein a first switching means controls a second switching means for preventing and automatically restoring electrical power from said outside source of electrical power to said electrical system of said transportation vehicle.
