RED PHASE COUPLING TX 4023

1.0. BRIEF DESCRIPTION.
The Model 4024 and 4024B Injection Units are designed to produce maximum power output into an 180V, 1500VA load. In normal field use the impedance of the earth circuit under investigation can vary considerably. Typically the earth test circuit consists of the earth grid under test connected to a remote earth grid through an earth path in the ground. To complete the loop, a return connecting path isolated from earth, usually an ‘out of service’ feeder, is also used. The earth test current is driven around the loop by the secondary winding of the Model 4023 Coupling Transformer which is inserted into the loop. The primary of the coupling transformer is driven by the Model 4024/B Injection Unit Amplifier. Inside the 4023 various secondary taps are brought out to terminals on the front panel via the selector switch. When the correct tap is chosen the Amplifier sees a reflected 1500VA load and it can deliver maximum power.

Operation: Through rephase injection unit.
