Abstract

An electrical power distribution system for distributing electrical power from a source. The system includes one or more network circuits electrically connected to the source and one or more load devices electrically connectable to the network circuit. The system also includes one or more controllers for monitoring one or more preselected parameters of the electrical power. Each controller includes means for determining actual values of the preselected parameter, means for comparing the actual value to a preselected threshold value of the preselected parameter to determine a difference, and means for disconnecting the load device if the difference is equal to or exceeds a predetermined difference amount.

Claims

1. A method of controlling connection of at least one load device to a supply circuit for distributing electricity, the method comprising:

(a) determining at least one first actual value of at least one preselected parameter of the electricity;

(b) comparing said at least one first actual value to a preselected threshold value of said at least one preselected parameter to determine a first difference;

(c) comparing the first difference to a predetermined difference amount;

(d) disconnecting said at least one load device from the supply circuit if the first difference is equal to or exceeds the predetermined difference amount;

(e) when said at least one load device is disconnected, determining at least one second actual value of said at least one preselected parameter;

(f) comparing said at least one second actual value to the preselected threshold value to determine a second difference;

(g) comparing the second difference to the predetermined difference amount; and

(h) reconnecting said at least one load device to the supply circuit if the second difference is zero or less than the predetermined difference amount.

2. A method of controlling connection of at least one load device to a supply circuit for distributing electricity, the method comprising:

(a) determining at least one first actual value of at least one preselected parameter of the electricity;

(b) comparing said at least one first actual value to a preselected threshold value of said at least one preselected parameter to determine a first difference;

(c) comparing the first difference to a predetermined difference amount;

(d) disconnecting said at least one load device from the supply circuit if the first difference is equal to or exceeds the predetermined difference amount;

(e) when said at least one load device is connected, determining at least one second actual value of said at least one preselected parameter;

(f) comparing said at least one second actual value to the preselected threshold value to determine a second difference;

(g) comparing the second difference to the predetermined difference amount; and

(h) connecting said at least one load device to the supply circuit if the second difference is zero or less than the predetermined difference amount.

3. A method of controlling connection of at least one load device to a supply circuit for distributing electricity, the method comprising:

(a) detecting encoded data associated with said at least one load device;

(b) reading the encoded data to identify said at least one load device;

(c) determining a first preselected threshold value of at least one preselected parameter for said at least one load device;

(d) determining at least one first actual value of said at least one preselected parameter;

(e) comparing said at least one first actual value to the first preselected threshold value to determine a first difference;

(f) comparing the first difference to a predetermined difference amount;

(g) disconnecting said at least one load device from the supply circuit if the first difference is equal to or exceeds the predetermined difference amount;

(h) when said at least one load device is disconnected, determining at least one second actual value of said at least one preselected parameter;

(i) comparing said at least one second actual value to the preselected threshold value to determine a second difference;

(j) comparing the second difference to the predetermined difference amount; and

(k) reconnecting said at least one load device to the supply circuit if the second difference is zero or less than the predetermined difference amount.

(d) determining at least one first actual value of said at least one preselected parameter;

(e) comparing said at least one first actual value to the first preselected threshold value to determine a first difference;

(f) comparing the first difference to a predetermined difference amount;

(g) disconnecting said at least one load device from the supply circuit if the first difference is equal to or exceeds the predetermined difference amount;
