Primary current injection test system -Oden AT

Description

Primary current injection test system -Oden AT

Oden AT is designed for primary injection testing of protective relay equipment and circuit breakers. It is also used to test the turns ratio of current transformers and for other applications that require high variable currents. The system consists of a control unit together 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 even higher current.ODEN AT can be quickly assembled and connected. The control unit has many advanced features – a powerful measurement section for example, that can display turns ratio as well as time, voltage and current. A second measurement channel can be used to measure an additional current or voltage. Current transformer turns ratio, impedance, resistance, power, power factor (cos φ) and phase angle are calculated and shown in the display. Current and voltage can be presented as percentages of nominal value.

Overview of Oden AT

• Most Advanced Primary Current Injection Test System to simplify all types of switchgear and CT commissioning, ground grid, circuit breaker testing and more „
• Modular design to permit optimal user configuration of output current  unit size „
• Compact transport cart facilitates portability into switchgear rooms with limited space „
• Unique I/30 function allows the current to be pre-set using low current to prevent test sample heating, thus eliminating corruption of test result
