Internet of Things (IoT)

The Internet working of electronic devices embedded with electronics, software, sensors, actuators, and network connectivity enabling the objects to collect and exchange data.

Interconnected Equipment

Equipment which shares at least 1 common electrical connection other than the power wires. A printer and a computer share a “printer cable” for instance. Or, a TV and cable box share an HDMI cable.

An electrical component which opposes the flow of electric current. An inductor has the property of impedance, the opposition to the flow of electric current. Impedance changes value with the frequency of the applied electricity.

Similar to electrical resistance since it is a measure of the opposition to the flow of electricity. Impedance is meaningful only for alternating current, and changes value as the frequency of the electricity changes.

IEEE 587-1980, ANSI C62.41-1991

A technical Standard originally published by the Institute of Electrical and Electronic Engineers (IEEE) in 1980, updated in 1991, and now recognized as an American National Standard.

Unit of measure of the frequency of alternating current. One cycle of oscillation is one Hertz.

Ground Fault Circuit Interrupter (GFCI)

A type of duplex receptacle or device that shuts off an electric power circuit when it detects that current is flowing along an unintended path, such as through water or a person.

The designers of electrical equipment assume that equipment connected to the electrical ground wire are at “ground potential”, that is, all at the same voltage. When equipment is electrically interconnected with audio, video, or data cables, and surges or other noise is injected into the ground wire, ground contamination occurs.

Ground (Earth Ground)

For safety reasons (human and pets), electrical systems in the USA have a wire connected to earth ground at the service entrance. This “ground” wire is run along with the two current carrying wires. Most electrical equipment is electrically connected to this wire when a three wire plug is used to connect the equipment to the electrical power receptacle. This third, non current carrying conductor which is connected to earth ground at the service entrance of a building is often referred to as “ground”. Receptacles were not required to carry a ground wire until the 1960's. Therefore you may live in an older home that does not have a ground wire attached to the receptacles.

Grade A, Grade B, Grade C The Federal CID defined three grades of surge suppressors based on endurance testing at several surge test levels. Grade A is for 1,000 surge endurance with 6,000 volts, 3,000 amperes applied. Grade B is for 1,000 surges with 4,000 volts, 2,000 amperes. Grade C is for 1,000 surges with 2,000 volts, 1,000 amperes applied. This standard is no longer being used by the US Government but you may find it referenced in our older literature.
