Primary injection testing of protective relay equipment and circuit breakers Simplify all types of switchgear and current transformer commissioning, earth/ground grid, circuit breaker testing, and more Megger has specially designed the ODEN AT primary current injection test system for testing circuit breakers (CBs) and protective relay equipment. You can also use it to test the turns ratio of current transformers and for other applications that require high variable currents. Additionally, you can set the ODEN AT to test circuit breakers with reclosing relays and sectionalisers, and it is ideal for performing heat runs as the current can be applied continuously or through programmable intervals. The ODEN AT can also test the integrity of earth/ground grids and safety-ground devices. The system consists of a control unit with one, two, or three current units. The current unit has three versions: S, X, and H. The S and X current units are identical, except the X unit has an additional 30/60 V output. The H unit is rated for an even higher current. These current units make it possible to configure the ODEN AT system for various tests. The control unit has many advanced features, such as a powerful measurement section that can display turns ratio and time, voltage, and current. You can also make use of a second measurement channel to test an additional current or voltage. The ODEN AT can calculate the current transformer turns ratio, impedance, resistance, power, power factor, and phase angle. The current and voltage can be presented as percentages of nominal value.
