The IEEE Four-Node Test Feeder

Unlike other, this feeder was not among the initial arrangement of test frameworks distributed in 1992. The basic role of this test feeder is to give a basic framework for the testing of all conceivable connections of the three-stage transformer. Qualities of the feeder are:

1. Double line sections coupled with a bank of a three-stage transformer linked between the two portions

2. Data specifications are done for "shut" connections for a three-stage transformer, as well as for two "open" transformer connections

3. Transformer information is indicated for step-down and step-up testing.

1. The principle voltage is constantly 12.47 kV while the auxiliary voltage can be 4.16 kV or 24.9 kV.

4. Information is determined for adjusted and lopsided loading at the furthest nodes

Test outcomes the above feeder incorporates the accompanying transformer connections for step-up and step-down operations, as well as for the unbalanced and balanced loading. Information for five diverse test feeders was created. Information showing up in this paper is "normal" to the majority of the feeders. The aggregate information for the 13 hub test feeder is incorporated to show the type of the information for the other test feeders.
