Megger ODEN AT Primary Current Injection Test System
Techno Master offer you Megger ODEN AT Primary Current Injection Test System in Egypt.
A powerful primary injection test system for protective relay equipment and circuit breakers, also used for current transformer turns ratio testing and other applications requiring high variable currents — a control unit with one, two or three portable current units (S, X or H versions).

Primary injection testing of relays, breakers and current transformers
Testing capabilities
- Primary injection testing of protective relays and circuit breakers, plus CT turns ratio testing
- Powerful measurement section displays turns ratio, time, voltage and current; a second channel measures an additional current or voltage
- CT turns ratio, impedance, resistance, power, power factor (cos φ) and phase angle calculated and shown directly
- Polarity testing with phase displacement display and clearly marked output polarities
- Heat runs with continuous current or programmable intervals, with times in minutes and hours for long-term testing
- Automatic recloser and sectionalizer testing — operating limits, partial and total times, operations before lockout, user-selectable reclosing sequences
- Ground grid and safety-ground integrity testing by current injection and voltage drop measurement
- Fast-acting hold function freezes short-duration readings on the digital display
Manufacturer-published capabilities. Available tests depend on the selected configuration and accessories. Confirm suitability, availability and pricing with our technical team.
