Identification

A specific electrical element or set of electrical elements that are connected together to form a fixed arrangement and used as a substitute load for terminating an electrical circuit. A dummy load contains all the essential electrical characteristics necessary to terminate the circuit but does not function in the same manner as the load which it replaces. Examples are resistors used to replace antennas, batteries, loudspeakers, or the like. Includes single port terminations of twin lead, coaxial and waveguide transmission lines as low power terminations of a section of a transmission system in a specified manner. Includes dummy loads when arranged in a group or bank. Excludes:power absorbers. See also load bank, electrical.
