Megger ODEN 400V AT/S/X/H Primary Current Injection Test System - Choice of Control & Current Unit

The Megger ODEN AT primary current injection test system has been specially designed for testing protective relay equipment and circuit breakers. It can also be used to test the turn ratio of current transformers and for other applications that require high variable currents. The ODEN AT can also be set to test circuit breakers with reclosing relays and sectionalisers and is ideal for performing heat runs as the current can be applied continuously or through programmable intervals. It is also capable of testing the integrity of ground grids and safety-ground devices.

The system consists of a control unit with one, two, or three current units. There are three versions of the current unit: S, X, and H. The S and X current units are identical except that 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 a range of different tests.

High current output - ODEN AT systems for 400 V, 50 Hz

The control unit has many advanced features, such as a powerful measurement section that can display turn ratio as well as time, voltage, and current. A second measurement channel can also be used to test an additional current or voltage. The ODEN AT can calculate the current transformer turns ratio, impedance, resistance, power, power factor/tan delta, and phase angle.

The current and voltage can be presented as percentages of nominal value. It also has a fast-acting hold function that freezes short-duration readings on the digital display, so when the voltage or contact signal arrives at the 'stop' input, the object under test interrupts the current, or the injection is stopped.

All parts are portable, and the ODEN AT can be quickly assembled and connected. An ODEN AT system consists of a control unit and one, two, or three current units. There are three different versions of the current units: S-unit (standard), X-unit (extra 30/60 V outlet), and H-unit (high current). The system designation indicates the number and version of current units included.
